Bob,
this is a great thread...
It's kinda funny, but when I got my son racing about 5 years ago (He's 15 now) I told him to work on being consistant and learn to drive with patience.
After every run - LOOK at the score sheet for 5 things.
1) Your FASTEST LAP
2) Your SLOWEST LAP
3) The TQ's FASTEST LAP
4) The TQ's SLOWEST LAP
5) Your Overall Consistency
Study those times - learn where you've made mistakes...fix those mistakes BEFORE you ask ME to make your car faster.
Work on DRIVING, HANDLING and CONSISTENCY...and slowly we'll keep adding power as needed.
I'm always suprised by people who only compare their FINISH time to the Winners FINISH time w/o comparing laps and consistency and taking into account all the errors in driving...and complain they had a SLOW car (When their lap times sucked)
