A certain amout of measuring is what testing is for. However, at this late stage you work on more practical and pressing matters, such as getting the speed out of your car in racing and qualifying trim because you have such limited time. You can't do that if you've got devices hanging off the back of your car and you're looking at other things. You can't change something fundamental if it doesn't work now.
They need as much baseline data now as they can get.
As said many pages back, data being useful depends on it being relevant and you being able to do something about it. In a sport like Formula One, data collected now is hardly going to be relevant in a few weeks because the window changes so fast. It also won't help you change anything fundamental with the car. Either it makes a difference to the time or it doesn't - that's what testing is for.
There is no in season testing to get more data later, other than very limited straight line tests.
Yes, which is why they don't have time for R and D projects.
Out of curiosity, should they just eyeball it, or ask Lewis if it is working based on his butt dyno?
Assuming that's what it's doing, but we have no idea that is what they're trying other than a comment from someone a few pages back.

The bottom line is if it makes an appreciable difference to their times with and without then it's worth doing, as long as it's positive. If it doesn't then it realy doesn't matter what other measurements they take. I just see this as another McLaren data overload trip. If it doesn't work then why has it made it on to the car?
Define appreciable. A 10th is huge. Races have been won by less, and qualifying has been won by less.

We already went through all this, and you are so wrong. Measure, quantify. Guess what, Mclaren knows what they are doing, and you clearly don't. Of course it's R and D. No car is done until it turns up at the last race. This isn't a new Spam can design, that they have to get right once and churn out a million. Each F1 team is a huge R and D project, from day one until they close the doors.

Why can't you change something fundamental? Last years car was fundamentally flawed, and by the end of the year, it was fundamentally fast. There are grey areas, everywhere. It is not often black an white.

They say the definition of insanity is doing the same thing over and over and expecting the same results (you in this thread trying to convince us Mclaren are idiots and don't know what they are doing) and the thinking in absolute extremes (you say leopards can't change their spots or instruments mean mistakes).

Those can argued to be passive systems influenced by external factors, and even then we've had a few bannings.
With a driverride height adjust system you will get away having a pin that holds the rockers in one postion and when its removed the rocker slips into another positon lowering hte ride height. Its a not return system and therefore there is no feedback loop and hence not actove control and therefore legal.
If it's a passive system then you might get away with that, but if there is driver input of any kind then it's illegal no matter which way you cut it.

I disagree, there are many systems on an F1 that are driver influenced but not "active control".
The only exclusion in article 10 is "no changes to the suspension system are allowed while the car is in motion."
This does not exclude a system where the driver can alter the cars ride height while it is stationary in the pits.
So your arguement around driver input has no baring in this matter.

In fact the rules does not specifically prohibit changing the ride height while in motion either because any activation of the suspension changes the roll centre and that can be argued to be an alteration while in motion. what you have presented is merely your interpretation of the rules.

The safe way is for a driver operated device in the cockpit that can be activated when the suspension is unloaded in the pits.
but I am pretty sure it could be successfully argued that a passive system can be activated by the driver while the car is in motion.
Platform dampers are allowed and those change the state of damping while in motion.

The rules intention is to avoid active systems working off a feedback loop but does not ban reactive systems.

But it won't be passive if the driver activates it. Ideally it is should be influenced only by the conditions around it. But I agree with everything except that the driver can flip a switch or push plunger or pull a pin (or whatever).

Does it actually make a tenth's worth of difference for the effort that it seems to be making? That's the only metric that matters right now. Given that they still don't even know if it's working right then I'd say they've no idea how much it will give them.
We already went through all this, and you are so wrong. Measure, quantify.
No. It's measure, quantify, check and action. The latter is the real kicker, because without it the former three are useless. I still question the whole 'data gathering' thing at this late stage. It's highly doubtful they're going to turn all that data they seem to be gathering into action. It will take weeks - if the data is actually still relevant by then.
Guess what, Mclaren knows what they are doing, and you clearly don't.
They might, they might not. McLaren has a history of gathering a ton of data at the expense of many other things, and I still question it. "They know what they're doing" is probably not why any of us comment on this forum. A lot of organisations are rather data obsessed, so it's not an unusual thing.
Why can't you change something fundamental? Last years car was fundamentally flawed, and by the end of the year, it was fundamentally fast.
It wasn't actually. They managed to throw together some improvements with the resources they have, and KERS gave them a huge mask, but there was no way they were going to catch up with Brawn or Red Bull. Fundamentally, the car just wasn't up to it. It's virtually impossible to change the philosophy of a car after it is built given the complexity and the work that's already gone in. It's like trying to turn an ocean liner.
They say the definition of insanity...
Uh, huh. I didn't actually say McLaren were idiots, but I'll skip. If you've got something useful to add be my guest.
....and the thinking in absolute extremes (you say leopards can't change their spots or instruments mean mistakes).
Formula One is a world of absolutes. There is precious little grey. You either win or you don't. There is goodness knows how much collective experience behind the phrase 'leopards don't change their spots'. It's why it exists. If you don't have that then I suggest spending your time more wisely on some life experience.

No, I didn't say that the use of instruments means mistakes at all. I question prioritising measurement at this late stage. In this case the phrase 'you don't fatten a pig by weighing it' seems appropriate.
Testing is for testing things. They are 'testing'. ](*,) ](*,) ](*,)
Testing is for testing and proving development (which is a good use of instruments given the circumstances) and testing what they will do in qualifying and races when they don't otherwise get a chance. McLaren appear to be developing.

A 10th of a second a lap is what, 6-7 seconds over a race distance? Oh that's not worth pursuing at all.

You got laughed out of this thread for thinking that Mclaren are panic measuring, by experts, but here you are again.

It's a shame, you have some good posts until you start arguing, and the cookoo clock goes off. :lol:

And on the check and action front, what should they do for chcking and action, at the track? Make a new wing out of duct tape and paper?

Think about it.

This is specifically to do with the ride height and suspension and not other systems on the car which may or may not be actively controlled.

That's the only way it could be done - but that wasn't what you were arguing before. Even then, it's highly unlikely that a driver initiated system would be allowed since it could be used while the car is in motion. You can't just say "Oh, we only use it when the car is stationary at a stop". That tac has been used before.
In fact the rules does not specifically prohibit changing the ride height while in motion either because any activation of the suspension changes the roll centre and that can be argued to be an alteration while in motion. what you have presented is merely your interpretation of the rules.
A clear distinction can be made between passive and reactive suspension travel and the set, default ride height of the car. You're rather splitting hairs now. That's how there are regulations on the ride height of the car but suspensions can be allowed.
The rules intention is to avoid active systems working off a feedback loop but does not ban reactive systems.
It doesn't matter what the intention of the rules is, they are clear, and no you can't get around them by arguing you have something that isn't active. A reactive system is unlikely to be successful anyway since setting the default ride height of the car requires a non-passive system of some kind to change the baseline.
In response to the text in bold. I have never once stated that the car had to be moving. I merely stated that the ride height could be changed by the driver. Assumption is the mother of all f*ck ups.

Then is response to your rigid stance on driver adjustable ride height.

Many systems on a car skirt the letter of the rules, DDD are a case in point. Those are clearly are not in the spirit or the intention or the letter of the law yet every car now sports one. Innovation is about spotting loop holes or opportunities that can be exploited in the rules, and on the matter of the driver adjustable ride height the rules are not clear.
There is no rule that clear states the cars ride height must remain constant for the duration of the race and this may only be influenced by aerodynamic forces or forces from the road.

I don't buy your arguement at all.

Also it is very simple to design a one way adjust system that can be demonstrated by design and practice to not activate (nor possible to )while the car is in motion.

Your passion for following the rules is noble, but a little naive. All these cars are designed to be on the border and often when a boundary is broken its a matter of interpretation as to whether the rules have actually been broken or not.

I apprepriate your challenge but its rather lightly constructed

Conni,
It is possibleto design and build a new wing within 4 days if you can run 3x8hr shifts.

Design can take one shift if you know where you need to be going in terms of design concept.
the design can be validated in CFD in a few hours
Mould construction will take the bulk of the time even with a CAD/CAM system in place.
carbon layup and autoclaving (curing) will take a full 24hrs but that can be rushed down to around 8hrs if you comfortable with the risk of endng up with a more brittle component than intended.

Possible, but probably not desired to crash the critical path for a project like this.

Think about it.

the real problem is :how could you possibly quantify an imrovement of 1tenth of a second per lap on a test environment we currently see?
We have conditions not representing what we will see in the first race ,be it air temp,track temp,road surface ,not even final specification of the car you will run.
add to this the variable of tyre/tire manufacturing it is rather obvious that those minor optimisations are dodgy to validate at best as the variables in your experimente are bigger by a magnitude than the possible gains you are looking to find.Exactly this is the reason why teams get lost somewhere on their trip in development.They take things for granted when a final decision of the true value of the modification can not be valued objectively.If you make a distinct step forward wich is reapeatable under each and every condition or at least you know under wich exact conditions to use the mod and when to avoid then you are getting there.

As far as I can figure out, Button and Hamilton are doing the action bit. The team can still do their tyre and set up evaluations. It just happens that a geek has stuck a measuring device on the car, and it probably makes negligible difference to the car's performance.

Just like another geek has stuck on various ducts to plan ahead for the hot races.

Yes turning data into action will take a couple of weeks. Just in time for the inevitable aero update in Australia, Malaysia or China
