PNWC GT Mod Performance Curves

Slow weekend here, so I thought it would be a good idea to plot the performance curves for drivers in the PN World Cup Finals, in the GT Mod category:

Ok, these guys are pros, take a look at how flat the curves are. The winner (Chad) was able to run close to 80% of his laps within a boundary of no more than 0.5 seconds above his best lap.

Just for comparison, I'm reposting below the curves from our last event, in the LM category:

The track layouts were completely different so it's hard to compare. I tried to adjust the scales to make the comparison easier.
