From the look of this, Hamilton should've been kept out on the super softs so he could make the two stops on the Medium.
He was getting quicker and quicker on them after the graining phase was over and the other teams weren't going that much quicker on the mediums. If he could've done four or five more laps they would've pulled off the two stop and I think a podium would've been on the cards for sure. I'll be really interested this weekend to see what happens because if there's no graining, the car looks good on race pace.
Drivers tend to push at the end of the stints before they come in, so thats why you tend to see some quicker times there. It may look like the tires weren't falling off, but I'm sure they were. The supersofts are NOT a good race tire. I think its unlikely they could have gone much more than a couple laps more on them, much less 4 or 5. They probably would have started losing a ton more time to the people who pitted for fresh tires.
Mercedes went longer on the supersofts than anybody else, so they did what they needed to there for the possibility of 2-stopping. What hurt them was a lack of pace. No point in trying to do a stop less when you're losing half a second a lap.
I'm 90% sure Lewis finished as high as he could with that car. 2-stop or 3-stop, wouldn't have made a difference. They needed more speed to finish higher.
