The math does not and never has dealt with the redistribution of grip. That is the basic problem with the math and where book knowledge falls on it’s face.
IMHO, the fastest line is always on the edge. But to get to the edge you have to have the luxury of time to increase speed, limit grip or increase hp. Most of what everyone races can only get to the edge by limiting grip. To limit grip it is mandatory to take into consideration the redistribution of grip.
or it don’t… ? :) I ain’t never sure about anything, I just once in awhile try to talk like it.
