well, i think the x amount of time per run group is a good idea but then, the people who need the time the most wont get it but....
advanced drivers need lots of time as well to fine tune lines/angles/transitions... just because a car is sideways 80%+ of the time doesnt mean the driver is satisfied with his/her driving. there is always room for improvement.
example, they dont give the kid with a 2.2GPA(novice) more time on the SAT than the kid with a 4.0(advanced) - just cause your slower doesn't mean your entitled to have extra time. you all get all the questions, if you dont get as many done(laps) in the alloted time, get better.
time is the reward for skill. goto more events get better, goto autox- its MUCH cheaper and MUCH more often. learn lines/throttle & braking/cars limits then pay the 100$ and use the track time wisely.
im not trying to put down the beginners but when i try to get friends/family to watch an event and i can only drive about 15/20 min every 3 hours- they dont like to attend.
we have all been down the beginner path. good luck.
