I did a do:
Under the drivers' names are their laptimes in all quali sessions, to the right the improvement from hotlap to hotlap, one further to the right the improvements from session to session and at the bottom the improvement from Q1 to Q3
There's a few things worth noting looking at the total improvement from Q1 to Q3
-Vettel improved more than Kimi but Kimi started on a better lap in Q1
-Dan couldn't extract the same performance from the car as Max (started on similar times in Q1)
-Lewis, Max and Seb improved by a similar margin
Looking at differences between Q2 and Q3
-Lewis did not improve from Q2 to Q3 on his first run
-Seb's first lap in Q3 was slower than his glory run in Q2
-Lewis' improvement from Q2 to Q3 was just 0.2s better than Kimis
Lewis improvement on his last lap in "party mode" only looked as massive as it was on the timing monitor because he did not do a second run in Q2 and did the exact same time in Q2 as on his first run in Q3 - and this is the only reason why there's such a wild discussion about the engine mode ...
It's pretty much "one chunk vs. several steps"
Another thing worth keeping in mind is that Lewis put all his personal best sector times into this one lap and made no mistake whilst Max and Seb both lost some time (was that roughly one tenth for Seb and two for Max?)
Max' improvement from Q1 to Q3 was pretty much the same as Lewis' who supposedly ran the "party mode" in Q2 and in Q3 (Wolff only confirmed he used it in Q3 but never implied he did not use it in Q2) - if you substract two tenths for Max' mistake he would have had the biggest gain from Q1 to Q3 and only 0.15s to Lewis from Q2 to Q3
Unknown factor is the difference in laptimes between the compounds but Red Bull did a huge step from Q1 to Q2, that's why i also did the Q1 to Q3 comparison because Q2 doesn't matter in that one
