1. "3 times one of them failed to make it to Q3 and then the Q2 times were used instead" - it's a bit apples to oranges don't you think? Especially with Merc cars that had more or less guaranteed Q3. Purpose of Q2 is to get into Q3 possibly saving tyres (2013) not to prove outright speed between drivers. Of course reasons for not getting into Q3 might be different altogether, perfect example Germany 2013. This is even worse:
2. 68.974 69.092 Q2 0.998292
How convenient when Hamilton makes it into Q3 and fails to make a time let's use Q2 times. What exactly is compared or proved that way, that failure is rewarded with questionable "driver's speed" statistics?
Isn't it obvious what is compared? The driver's qualifying speed is compared. But if it makes you happy, feel free to do the same calculation excluding this track. Just go ahead and eliminate Germany 2013 as well, if that's important to you, and present us the overwhelming difference it makes.
Other factors like missed whole or part of P3 that made it impossible to work on qualifying set up (Rosberg Italy), other car problems or team failures are excluded but driver's failure in Q3 is included. So let's say it's the same if Rosberg doesn't make it into Q3 in Germany 2013 because of team's error and Hamilton can't make a quick lap (Italy 2013)?
I am not talking about driver errors or performance in general. I am talking about qualifying speed, as a response to some earlier claims that the speed difference has increased from last year. In 2013, there were 3 examples of one of the Mercedes drivers not making it into Q3. In those cases, the Q2 times were used instead, as they are the best possible measures available to compare the drivers. The fact that one driver doesn't make it to Q3, usually indicates that the driver's effort is of importance even in Q2 and it makes no sense to assume that the drivers are not doing their best in Q2 as well. Team errors may occur, but they are rare and won't make a big difference when looking at the bigger picture and they tend to even out between drivers over time.
In Austria Hamilton didn't get a time in Q3, so Q2 was used. Mercedes had more than half a second to the 11th fastest time in Q2, so maybe they were playing it a bit more safe there. However, my impression is that Q2 is used by the drivers as a rehearsal for Q3 and the speed difference in Q2 is generally representative for the speed in Q3. Maybe I will post some statistics on that as well if you don't believe it. I am pretty sure that Q2 speed difference generally correlates well with Q3 speed difference. In Austria Rosberg improved his time from Q2 to Q3 by 0.030 s, so I doubt he was holding back much in Q2. Other drivers typically improved by a a couple of tenths, which can probably be explained by improved track conditions.
I am not sure exactly what your point is here. beyond trying to argue that statistics are lies. Are you claiming that the speed difference between Hamilton and Rosberg has changed from last year? All I am saying is that the numbers don't back such a claim and numbers don't lie. People who interpret numbers may lie or they may do mistakes in their interpretations, but I haven't done any such thing here. I am simply stating some pretty basic facts which show that the relative speed difference on average is the same so far this year as it was last year. Hence there is nothing that supports a claim that the difference has changed.
