Interesting... I run this track, and we go the opposite direction, and use an additional chicane on the back straight. Pocono is kind of a boring track, very long and unchallenging, full speed in my car down the front straight, just cruising awaiting the 1st turn
I catch myself daydreaming.
I do like the twisty part of the course, but don't go off course as it is very rough.
To me it looked like he put the VDC on the last turn as it is fast and he didn't want to oversteer coming out and potentially wreck, and then he turned it off again on the straight.
