LRP. Braking after the downhill turn Apex????
So found this video of a guy setting the lap record in a Skip Barber race. Looking at the video and data it looks to me like he eats everybody's lunch on the downhill turn because it appears he accelerates all the way to the Apex and THEN brakes slightly.
That can't be right! What am I missing?

He's definitely not braking down there. Scrubbing off some speed as the wheels are turned - yes but he's definitely on the gas at the apex.

I took it flat out in a Skippy car during my 3 day racing school (trying to imitate Carl Lopez in Going Faster)...... it didn't turn out so good..... at least for the skippy car.....

JP66, the answers others have posted don't tell the whole story.
Drivers need to be careful when attempting to follow other driver's advice, especially in this area of the track.
Exit speed from West Bend, where and how long drivers shift up, how long the throttle is not at 100% from turn-in at West Bend to braking at Big Bend are all very important factors to how those drivers ostensibly "do the Downhill flat."
When viewed more completely, this can be very illuminating. And it can puncture this urban myth that you can't have a fast lap without "going flat" down the Downhill. Too many similarities with Turn 12 at Road Atlanta... Same deal.
There are certain, specific methodologies pro and accomplished am drivers use to build up to the point where the percentage full throttle over this entire section can be incrementally improved, but please, DO NOT change what you're doing just because you read on Rennlist that others "do it flat."
I love all you guys (and know most who have posted), but my several hundred megabytes of data in a variety of cars (including my own experience there over the last thirty years, in about four dozen different cars) indicate that there are a tremendous number of "degrees" in "going flat" down the Downhill.
And many that have done it once, CHOOSE not to do it every subsequent lap...
Sheesh...

The fact is that you need to time your throttle lift (to a 1 or 2 pedal) and subsequent turn in as you hit the compression perfectly and brush the curbing at the apex. There are massive consequences if you mis any of those.
BTW - This is the same as going up the Esses at VIR "flat out" or T12 at Road Atlanta.
