Any V6 manual drivers who autocross?

I've been to an autocross event at Santa Maria Airport, CA where there were two tight hairpin turns where my speed dropped to as little as ~20 mph. Since M6 tranny in the V6 engine tops out at 40 mph, I thought that heel-and-toe downshifting into 1st before the apex of these tight turns would make my run times faster.

However, it was exact opposite: no matter how well I nailed the turn or how fast I could do a 1->2 shift, I would lose 1.5--2 seconds to keeping it in 2nd gear all the way (on a 65 second course).

What gives? And do any other V6 drivers keep their cars in the 2nd gear all the way?
