Ok, maybe I AM glad I asked the question… I think I’m starting to understand what you’re saying – finally!
Sorry Paul, but you have a tendency to get side-tracked in a lot of your responses, which makes it hard to understand what you’re trying to say at times, and that’s why we’re on page 3… I’m glad you kept going though because I’m always game to hear more ideas that might help me learn more.
Anyhow, I’ll agree with a few things you said…
1) It’s possible to maintain speed after decelerating, up to the point where you accelerate again, being at the limit of grip all the time – that should be obvious.
2) (SOMETIMES) It’s possible to take the same corner, on the same line, faster by being on the gas earlier because the acceleration forces will transfer weight – this might not be obvious to everyone, although I’d think that most people who have raced for any length of time should recognize this… hence, I’m not sure that it’s really “magic”.
So why is it only “sometimes”? Well, (ignoring the driver) things like kart setup, grip in the tires, grip in the track surface, etc., all play a role.
What happens when you go into a corner, decelerate, apply throttle, and the back end steps out on you? What happens when the front won’t turn anymore and the kart hasn’t rotated enough to make the corner exit?
This really has nothing to do with “slow in/fast out” concepts and everything to do with kart setup… which is why I think this has been over-complicated.
The fastest guys in any form of motorsports have 2 things going for them. First, they’re talented. Second, their car / kart is handling well. The middle of the pack guys are lacking in one of those areas. The back of the pack is lacking in both those areas or is seriously deficient in one area.
When you’re busy watching, look for the middle of the pack guys who try to apply the “magic”, but end up with karts that won’t respond to the driver inputs the way they’d like them to. It’s not just driving skill that allows the “magic” to happen.
