Not too concerning for LEC, he stayed out 6 laps instead of 3 and did his best time on his 5th lap instead of 2nd like SAI. He had more fuel for his lap in general.

Race sims:
I don't think Merc or McL did any race sims, they just did laps around at varying speeds and such. It's encouraging from Ferrari.
