Edit: LVDH I have just seen the results on the challenge page and I think you have miscalculated my result. I used the same car as last race so I should have a cl of -2.407
Maybe you need to do the results again
I just checked; The numbers LVDH sent me to do the video were correct (Cl.A = -2.407), so the video is correct.... your time is 3:27.02.
Just a copy-paste error on the website I guess...

Good news, all the books have been sent, including those for Brazil and Australia, which will probably be delivered in the first week of 2018.
The first prize (wich belongs to JJR) is now in Milton Keynes.
I realized that our challenge is truly extended to the whole world
I hope to have people from China and Japan next year.

Well happy with another 6th place championship finish. Thanks to everyone behind the scene and the other people who compete.
Really impressed with the performance of the intro class Brook_Motorsport and his constant improvement.
Looking forward to a break but itching the use my time off for some development!!

Somehow I get the feeling Brook's lift/drag values are in error on the LM sheet. Have a good look at them.
(And yes, I started lurking just to make a nuisance of myself, sorry)

Should be identical to the previous round as it was the same car

Copy-paste failed them this time.

Yeah, it looks like there are a few copy-paste errors in the table... but the data LVDH sent me to do the video looks correct: e.g. the data I used for Brooke Motorsport was the same as was used for the previous round.

Hi guys,
I finally checked all numbers. Somehow with SHM at some point the down force coefficient got overwritten with a wrong value. I do not know why, as I always copy entire rows...
Well to make things worse though, I messed up MercuryMotorsport's lap time. These are written by hand after using the MVRC Timing app. Here the mistake was ten seconds, pushing Mercury one position up. In the championship it did not matter though.
Sorry for the confusion, I will make sure to relax the next days. The page is updated with the new numbers.

I received my copy too. I did not expect the book has so many pages.
Did you notice that the "Valkyrie" has a "Mantium" diffuser (see the 2015 KVRC season)?

While my book has not arrived yet, I can almost image what this diffuser will look like. Once more someone else had one of my brilliant inventions before me. Somehow that is how my life goes.

Maybe he saw it here on this forum?! I'll vouch for you Andre; it's your design and he copied it!
