Sigh. The term raw speed is applicable to what you show during multiple tries in qualifying.
I notice you sometimes (often?) try to complicate things a lot, and lay down your own criterias for what should be the game of the discussion, that's fine but you're running the risk of standing on your own top spinning.
I'd argue I'm not introducing complication. F1 is an extremely complicated business to begin with and I've merely tried to point out some of the ways in which that's the case and to argue that there's no foolproof way of establishing, from laptime data alone, the comparative raw speed of two drivers even if they're racing in the same teams under, as near as possible, the same conditions, because you can't isolate what the driver puts in in terms of his pure natural ability and speed, from other facets of what the driver brings to the table in terms of his setup choices, racecraft, consistency etc, nor can you isolate it from outside influences. And even if you could, in principle, isolate raw speed from other facets of driving skill and ability and from outside influences, it wouldn't be of much relevance because, as Butoneer correctly pointed out, all that matters is what results a driver is able to get from whatever equipment, ability, talent, opportunities etc he has at his disposal.
I would be perfectly happy, however, to let you bring in whatever laptime data you think is relevant to this thread without quibbling, if you were not so bold in your claims that it demonstrates, in quantifiable terms, the relative raw speed of Button and Perez. If you're now saying that all you mean by that is that it shows you who is quicker on average over multiple tries in qualifying then of course I readily accept that, if that's what you're measuring, then that's what the data tells us. But I don't accept that if Button is a shade slower on average over multiple tries in qualifying, then he is inherently slower than Perez, for the reasons I've mentioned.
