Doesn't feel accurate the Hungaroring, Bahrain, and Suzuka are the lowest grip circuits due to the grade of asphalt they used to construct them for various reasons (Hungaroring build in soviet times, Bahrain very hot summers and sand, Suzuka old track).
Hungaroring Piastri was 0.6 behind Norris (after thay gave Norris the preferable strategy)
Bahrain Piastri won 16 seconds ahead of Norris in 3rd.
Suzuka Piastri was 1 second behind Norris and 2.5 behind Max (after they wouldn't swap to let Piastri have a run at Max).
Of the remaining
Brazil - high grip surface
Vegas - high grip polymer applied over the asphalt
Qatar - low/medium grip surface
Abu Dhabi - high grip surface
So even if Piastri struggles with the low grip surfaces he should be fine for the rest of the season.
