I think in general choosing down, especially in the 3rd period is way overdone. As is deferring. Sure, having more information going into the third might help, but maybe it's also easier to get that escape point in the 2nd when you're closer to being fresh than starting the 3rd.
For TB, 30s is indeed pretty short. I wonder if anyone has stats on the ride outs end up, like how baseball coaches play the averages with calls. Seems that most wrestlers just default to thinking they're a good wrestler, so they can get out and just choose down out of habit.
