It shows me what I did in each "element". As simple as, my first run I didn't really "launch" the car. But on my subsequent starts I did and gained around .2 seconds alone.
I also tried different entries/techniques in different sections and had those overlay each other with all data points available (speed, Gs) and could see where I was in relation to each one at any particular point.
So for the future, when I am at a particular "element" I can know what the fastest way (according to my data) through it would be.
The crazy thing is, that on my last 3 class runs I was within .03x of each other. And I tried a few different things during each run. I suppose there is something to be said for consistency.
I also got first-hand experience to the sensitivities that the MR-S has to changing conditions. My first TO in the afternoon was around .6 faster than my morning runs, and the car felt great!
