I think anyone who is serious and honest about almost any sport will tell you that personal coaching is helpful at all levels. If you're many seconds off a good lap time, coaching will likely lead to an epiphany. If you are looking for fractions of a second you want someone to help you keep from slipping back into bad habits or getting blasé about things you think you cannot improve upon.

The one thing I don't understand about the braking article that was posted is it talks about getting to full braking in .2 seconds and then modulating off from there. To me this almost seems to go against the concept of squeezing to manage the weight transfer and is more like stabbing. Could someone explain this a little more?

Thanks doll! Indy won't feel the same without you there...
Here's my question: can you (VR) FIT in a SM? I'd like to see you try!

This has been posted before, but here is a great article on braking http://www.optimumg.com/docs/Brake_tech_tip.pdf
If anyone needs help with the math channels for AiM, I can post them.

Ninety percent of the DE folks (and some club racers) I work with the first time show the reverse. They apply pressure on the brakes and end up with MORE pressure (hence more deceleration) at the END of the brake zone instead of the beginning.
The article states that there is a significant improvement realized IF max brake pressure is reached in short order, then tapered, rather than slowly developed and inconsistently continued.
Here is an awesome brake pressure trace from a pro at Road America into T12 (Canada Corner). The Speed, Throttle Position, Longitudinal G and Front Brake Pressure are shown. The time from no brake pressure to peak brake pressure (at 150+ mph) is less than .35 seconds and the pressure does taper, but is maintained well throughout this longer braking zone.
I have a very clear vision of what performance benchmarks drivers SHOULD be able to do. in every car, on every track. Few do this and fewer still do it well. That's why we come back... <big grin>
