What a horrible session for Max. Almost no purple sectors during his fast laps, very slow in the race stint, half a second on softs after S2...
Doesn't look good...
The McLarens didn't really push that hard anymore after a few fast laps on the hards / or made mistakes during later fast runs on the hard tyre.
He had similar S1 and S3 times to Russell on hard tyre fast laps and hard tyre race sim, but was half a second slower in S2 than Russell on the race sim. Looks more like grip / setup issues than fuel related.
S1 and S3 are very short and not that fuel sensitive, so time gaps are always pretty small there. Still, George had the edge there before his tyres fell off. If I had to guess Max was running race fuel (standard for RB) and George was running an in-between fuel load. Lower than race fuel, higher than sprint. He was too slow for sprint fuel loads.
Do you think it's that easy? Old floor is good, new floor is bad? I'm sure if that would be the case, the engineers at RBR would know it. I'm not worried because RB20 was pretty good here last year. And this car is better than RB20.
