[Pierre Caillet]

I agree with Michal. In general, it seems to me it still lacks aggressivity. I think you're a bit late on the gas in all corners except turn 3. And your acceleration is often hesitant because you're keen on staying well on track, but if you have to hit that curb, you have to. That goes for the inside curbs too. Zandvoort is not the kindest for those, but try cutting more in turn 6, first one in turn 9, and turn 10.
(and that shifting up to 5th gear right before turn 9 is superfluous)
