I've received feedback from reddit that I just picked a lap, my bad for posting interesting content on reddit, but...
The number of laps makes this telemetry a bit confusing but it's pretty easy to see that the behavior in the first 2 corners isn't just a case of a few laps, Leclerc is either braking earlier, from higher top speed, or braking a bit less earlier but shedding speed before the corner. This is true for both Tamburello and Villeneuve, overall I think I'm pretty convinced that this has to do with porpoising and controlling for the braking point in T2.
I find pretty interesting that Leclerc is experimenting 2 ways of cornering into Tamburello, either from higher top speed or from first shedding speed, probably a bit due to engine mode but certainly to save tyres in that braking point.
I don't think it needed further confirmation but I think porpoising really hurt Ferrari here.
