A few observations from the race based mostly on Sector times (largely excluding the 3rd stint as inconsistent traffic for both cars messes with the data a bit):-
Wear rates: For very 3 laps of wear the Papayas' accrue, Ferrari accrues 4. That seems pretty consistent across both Medium and Hard compounds.
- Norris was .5 faster on the Medium across the 1st stint and only 1/10th faster on the Hards. I'm measuring like-for-like during the Medium stint but, as Norris pits early, I'm cutting the comparison on that lap. For the Hard stint, I'm measuring Norris' first lap against Leclerc's first lap (and not offsetting for 5 laps less fuel in the Ferrari) so it's less representative. Norris also has a shocker on laps 28 and 40. But if I exclude his best two laps and Leclerc best two laps, the difference is still about 1/10th.
- Leclerc is pretty metronomic each lap whereas Hamilton is more up and down.
- Hamilton makes up about 3/10s in each of the pitstops (counting lap in and lap out). I don't know if that's down to the pitcrew times or the drivers as I didn't see the stationary timings.
- The time Leclerc gaps Hamilton in each of the 3 stints was 1.8 secs / 5.8 secs / 0.45 secs (I've excluded the last lap as people were obviously cruising).
- Hamilton experienced time drop off due to Deg a lap or so earlier than Leclerc in each stint.
- It would seem from both timing and the Radio that a big chunk of the time loss on Hard was due to Colapinto coming out in front of Hamilton on fresh hards, whilst Hamilton was 15 laps into his own Stint. Leclerc was lapping 1/10th faster each lap until then. Colapinto drops in and it immediately climbs to 4/10ths. However, it also corresponds to tyres going off on both cars (Hamilton complains about rear overheating two laps before, giving up almost 6/10ths to Leclerc that lap before bringing it back under control) and Leclerc picks up Tsunoda not long afterwards so I'm not confident that Colapinto entirely explains the gap.
- Hamilton doesn't ask if he can extend until lap 46 and he pits on lap 50. This suggests that he wasn't holding time in his pocket up until then. But it does suggest that he probably had more tyre life that he didn't use in those last four laps before he was pulled in. If we take Leclerc last 4 laps as a 'best case', Hamilton might have found as much as 2 seconds if he had stuck to the optimum pitwall strategy instead of hedging his bets.
- Curiously, both cars bang in an absolute cracker of a lap on lap 63. Hamilton had eased off four laps earlier (moving into the 69s), then put in a 68.242. Leclerc stayed in the high 68s all the way up until then, but also hammered in a 68.366. Then both cars immediately ease off for the last 7 laps.
