lap gap
1 1.599 SC
2 1.273 SC - Both drivers are told they'd do the swap later in the race (there ya go turbo :^) )
3 0.888 SC
4 1.159 Flying lap.
5 1.350 Charles says the gap to Hamilton is fine, Seb is being told to let Charles by
6 1.376 Charles is being told Seb will let him by that lap, after discussing with Seb it's supposed to happen the next lap
7 1.372 Seb is being told to let Charles by. Charles is being told that Seb will let him by next lap. Vettel says he should close the gap, LEC says it's too hard.
8 1.686 Vettel is told to let Charles by, ignores the message, Charles is told Seb will let him by that lap.
9 1.949 Charles is being told that they will swap later on.
10 2.164 Charles obviously drops back to get out of dirty air in the next few laps.
11 2.726
12 3.159
13 3.484
14 3.672
15 3.659
16 3.986
17 3.861
18 3.908
19 4.141
20 4.387
21 4.231
22 9.244 Pitstop Charles.
So, being 'objective' ... here's the key facts:
Leclerc stayed close to Vettel during the first few laps when Vettel was being told to let him by, he pushed hard on those initial laps, during the discussion when Vettel refused to obay team orders Charles still managed to stay within 1.3 seconds, dropped to 1.6 for one lap and the gap only opened properly once Charles got told that they'll swap places later in the race. At that point Leclerc only had to care about his gap to Lewis (team radio stopped mentioning the gap to Seb)
Leclerc did NOT overcook his tyres at a safe 2s interval that is 'outside the turbulent wake', he did it in the initial phase of the race when the place swap was planned.
Once he knew they would swap places anyways he gradually dropped back to around 4s on tyres that were already in worse shape than Seb's ... the last seven laps before the pit stop Charles was even quicker than Seb three times.
The actual 'safe' distance is more towards 3 to 3.5 seconds, not 2 (post race press conference - Hamilton: "When you're towing at two seconds it's quite hard to follow, ehm, so yea i dropped back to around three ... three point three or three point five seconds")
So counting from the 'safe' gap that Leclerc allowed to open Vettel needed nine laps to open a gap of one second which is a little over one tenth per lap "pace advantage" on better tyres........
