While I agree that points per season overall is a poor metric for the reasons you pointed out, I think, if he keeps the same form until the end of the year, it will still become extra proof of his dominance this season. If he wins the rest of the races his score will be so high that it would become s feat on its own if someone (not Verstappen) beats it within the next decade. Verstappens win rate right now is like 78% (including sprints) which means even if there will be more races the next person to beat his record would have to have at least around ~75% win rate. We know how good Hamilton is, the closest Hamilton ever got was 65% in 2020. There’s currently no other driver on the grid who is good enough to beat the record Verstappen is about to set.
