That makes sense Neil. I heard there was a lot of attrition also.
As far as understeer in T1 I've always found this to be a normal character "flaw" at VIR, even when the car tended to oversteer elsewhere. There's a lot of fluid laid down in T1 when cars first come onto the track so the area from turn in to apex tends to wash out front end grip. At least, that's what was explained to me by a local.
It's great to see the 1M representing on track. Heck, between your results in One Lap and now this I'm starting to think it might just be an M car after all.
