I want to compare race tracks by analysing how twisty they are.
This is interesting because some race bikes in the TTXGP races go fast in a straight line but have to go round corners quite slowly while others go slower in a straight line but corner better.
I am trying to think up a simple way to describe the twistiness of the track (in 2D is fine for the moment).
For example is there a standard way I can compare:
