Correct.

Can see the issue into T10 on the telemetry. It cost him 2 tenths to Perez.

The delta line on the straights is gently sloping upwards on all the straights after T4 before it turns upwards even more aggresively into T10. I suspect the issue began in T4 and got worse as the lap progressed.

Nah I'm certain what we're seeing is honda's mapping getting caught out by T9 (campsa) being flat out (or nearly) and not re-engaging the battery on exit, or something along those lines. I don't see a problem up to that point, and T10 is way too early in a lap to be running out of energy usually.
Verstappen was at 96% throttle going into campsa, but it looks like that's still enough for this to happen.
This happened already in australia during the race when ERS mapping didn't anticipate T5 eventually becoming full throttle as fuel burnt off. Verstappen was on the radio multiple laps that he's losing time there, then at first he was instructed to do a lift in T5 so that ERS mapping knows where it is on track, but eventually lifting was getting too slow so he was told to just use overtake from T4 to T6.
It'll be sorted for tomorrow.

Great insight.

Ferrari’s fastest laps were on used (already 1 previous hotlap) tires right? If so they are right there so far.

no, those were new. Ferrari (as the only team) used two sets of Softs, so they saved an additional set of Mediums.

Thanks dude. That makes a lot of sense. Never really thought about the mapping in this way

aston is very slow on straights, back to their pre-baku traits. super stable in corners, almost looks easy for alonso, but pays for this on straights.

One thing I noticed that's curious, both T1 and T7 are ~150 kmh corner yet max and fernando are reversed in terms of speed.
T1: ver +10 kmh
T7: alo +11 kmh

Long run times for the bulls:

Max (S)
1:21.0
1:21.0
1:21.0
1:20.9
1:20.9
1:21.4
1:21.0
1:21.2
1:21.0
1:20.8
1:20.7

Checo (M)
1:20.9
1:21.3
1:21.1
1:21.4
1:20.9
1:20.8
1:21.7* Was behind Albon the entire lap
1:21.8* Didn't push
1:21.8* Didn't push

They can all go home now and don't bother.

Verstappen's pace is frightening.

And if that was not enough, in his last stint race sim he did 9 laps on old soft tyre running a target time of 1.19.4 s/lap, then at the final 10th lap he just went to a mind-blowing 18.6 out of nowhere! Was that lap with DRS on and maybe assisted with a little help of a tow or he just simulated a hammer time lap-in for a pit-stop?

It was a normal lap I checked, but he could be sending it.

[atanatizante]

Has anyone have the lap times set by each driver on the T tyres?

the long runs you mean, I guess?

[atanatizante]

Thanks a lot! Do you have also the other top team drivers, please?

unfortunately not, no. All others were low/mid fuel runs only, so I didn't copy them to Excel.

[langedweil]

Indeed, 1:13/1:14 could maybe be possible, but there are a lot of variables at play.

Well, with a 1:13.907 in FP2 already, a low 1:12 / high 1:11 should be possible I reckon.

Laptimes listed are swapped here. Aston is slow on the straights but I think there are some conservative engine modes are in play looking at the telemetry.

I wouldn't worry about Ver in T7, looking at the onboard he hasn't pushed at all in the corner. Alonso carries more speed and runs all the way out onto the yellow sausage curb on inside of T8. Verstappen's passage is much more conservative.

Anyone else can see what this is talking about?
