Switching back from endless discussion on Max v Lando in mexico and the 'rules' (let's just accept that everyone has their own opinion, and that no amount of writing is going to convince anyone otherwise - even stewards are showing no consistency), coming straight to the WDC :
26+8, 26, 26+8, 26 on the table.
Realistically, RB20 is a P5-P6 car, even then it needs to beat atleast one Mercedes.
Let's say, on average, Max finishes P5 in every race (behind both McLarens and behind both Ferraris) - that means he bags 10+4, 10, 10+4, 10 in the next four races. That's 48 points. Let's say probably 40, if he maximizes the ability of the car but still has some bad pitstops or with the engine penalty, finishes P8 in one of the races.
What Norris has to do, is to gain 40+47(the current deficit he has) = 87 points. Let's say 25+6, 19, 18+8, 15 , which add upto 91 points, even with only one race win and one sprint win. Even if he loses 5 points out of this possible string of scores, still he wins WDC.
So, contrary to popular opinion, the pressure is actually on Max, to retain the WDC, not the other way around. Max has to not only do really well with the sub-par car (which is terrible on H tyre, whatever is chosen by Pirelli - C1 or C2 or C3) ; he also has to pray that both Ferraris do really well. All Norris has to do is stay away from dogfights with Max, he can easily overtake on the straights (whichever is the ckt, MCL38 > RB20 in any setup, any track).
I have a feeling that the final AbuDhabi GP is going to be a nail biter, like 2021. If any of these two drivers suffers a DNF before that final race, they can write off their WDC chances.
