does anyone use the black line as a reference point for braking and turn-in?
fwiw, that horizontal cement strip is a low spot, there is a drain somewhere.
If you ever get the chance walk that turn. eye opening!

Approximate, estimated from a few videos I took a second to look at...
From start of braking (more than .3g negative, longG) to
A) head under the driveover bridge (split 1) and
B) head under the pedestrian bridge (total)
The total is much better than guessing point of WOT because a) we don't have that info on some videos and b) it all works out by the end point! If WOT is sooner, the second split of the total segment will be better.

Sean Johnson 2011 ALMS Winter Test 997 GT3 Cup GTC, 2:10 6.8, 12.6
Clarke/Sly last week 996 Cup 2:16.9 7.6, 13.7

Juan Lopez-Santini 2-liter 901 2:25.5 8.1, 14.3
Rad 2011 Winterfest FIAT 2:21.7 9.3, 15.8
and 2-liter sports car 2:05.4 6.4, 11.5
A LOT can be learned from this study...

March 2012 FIAT 2:16.576 8.44 14.6 (still lots to learn).
My approach to T17 is pretty straight forward, enter slow, stay away from the walls, wait for straight, hit gas. Same technique at T1.

We'd need to work together sometime to find more time.
But with the MoTeC, I have worksheets that would find what you and I need to know to do that. I'll be at DMTD before PCA with Angus. Perhaps I'll see you on my way out Thursday.

Drifting
I think Grady (Red Bear) does some fun stuff in t17 - he stays on gas until past corner worker - drives in real deep - then slams brake, turns and hammers it. I am still trying to build up the nerve to do that.

I'm a big fan of going tight to the corner worker on entry. However, I've noticed that the 2nd corner worker (past the bridge) is better taken 1 car width off the apex. It much smoother track, and I'm able to get back on WOT much earlier.

Burning Brakes
My least favorite turn in all of Motorsports
Ended up on THE other side of the wall last turn last lap
Not much left of the skippy FF
Would have been 4th straight win in a row.......
Lost a lot of confidence for the next few races
Lost the championship to mr. Tony renna
