How do you know that Bottas wasn't four seconds faster than Massa over those 20 laps? how many times have we seen much faster cars being held up for lap after lap because of the dirty air coming off the car in front and go 1/2 - 1 second quicker in clear air. Mercedes themselves had that problem, making the undercut all important. It's a bold statement to absolutely say that Bottas wouldn't have pulled out a 4+ second gap over 20 laps, it's only 2/10ths a lap, it's more than feasible that Bottas had the pace to pull away at 2/10ths.
I know because Williams were doing the lap times they were expected to do during the stint and it doesn't take a genius to know, realise and see that slipstream effect is very high on this track.
Bottas was only fractionally faster with tow and DRS on a track with very little negatives from behind behind a car, they're is more positive than negative, the negative effect is between 2 and 3 seconds behind.
Massa was faster all weekend and had better long run pace than Bottas so I'm all likelihood Massa was actually faster and was only under pressure because of DRS and tow.
Bottas made the call on lap 9 asking about racing his team mate, so he would have been given the opportunity on lap 10
Mercedes pitted in lap 19, that's 9 laps to make up 4 seconds, Massa pitted on lap 21, so if that was Bottas that's 2 laps and Hamilton went 2 seconds a lap faster (all drivers were 1.5-2 seconds a lap faster on fresh tyres)
That means Bottas needed to be 4 tenths faster than Massa and Hamilton per lap, which is massively unlikely.
Now what about the fact that Mercedes were 6-9 tenths a lap faster than William's in qualifying/practice on the harder tire, they were also 2-4 tenths faster in free air (Hamilton vs Massa) in the race
Mercedes also pitted early because they knew that Williams couldn't pit that early because their tyres wouldn't last if the race was all dry.
Now as for it being wet, look how they lost tons of time per lap, Williams' car is awful in the wet, they ended up over a pit stop behind.
In every scenario Mercedes would have won, if you can't see, understand or comprehend that then what can I say that isn't rude/offensive.
