Question for Autocrossers

A lot of you autocrossers do not drive in our Time Trial series and I was wondering if you could tell me your personal reasons why not.
I've heard there are some good AX drivers who might appreciate the incredible amount of seat time we get (a whole AX season's worth in one TT), the ability to measure your improvement from season to season on a track that doesn't change, and the ability to repeatedly practice every corner on a track about 75-100 times in one weekend.
