What do you do in the off season to stay sharp

[Chad Rhodes]

I've had a practice tree for years, but never really developed a routine. I set my practice tree up on my desk with the pedal underneath. I created a spread sheet, which analyzes the data over every 100 hits (but does average the green lights every 10 hits as well). One of my new years resolutions is to take 100 hits at it every day. So far I've learned quite a bit about my own driving, what I've been doing wrong, and where some inconsistency is coming from. I haven't solved it yet, but i am seeing the patterns and noting what I'm doing differently. With lots of data, I've been able to find some things I was doing, that I would have sworn i wasn't. Hopefully I'll be able to eliminate my self from the list of variables on the starting line soon.

What are some of you guys doing to stay sharp, or improve yourself?
