I watched a couple of times yesterday.

I think their speeds are pretty accurate also.

Normally I am around at least 90 mph at Ricochet doing the 1.7.....and only ran the 3.1 a few laps while shaking down my CMC car and so I can't really say how much faster the 3.1 would be....but you have a longer straighter shot...so I am sure you would gain speed through that section

If you read the other link....the passenger said it was driver error. Sounds like he put two wheels off early and then in the process of tyring to correct the two wheels off.... ended up turning in for the corner too early.
