Excellent point! And its the one I was bumbling and struggling to make. I think Stoner and Pedro, and to a lesser degree Spies got the right setting or at least style to preserve the tires at Indy, which it seems was a bit of a "new" track (well, at least the surface was). Its not saying that Stoner isn't fast, as some have tried to poo poo the suggestion that tires were an extraordinary issue at Indy mistaking it for Stoner bashing (though the source is certainly known for it). But I completely agree, that's why I described the tire choice as oxygen or cyanide, or better put, the Ducati version of operating band--that is extremely narrow.
I agree with both of you, but have some sympathy with bridgestone who didn't really want a control tyre either, and may have produced the tyres at Indy in response to criticism of their tyres being treacherous early and too durable late earlier in the season.
As talpa says this is the problem with a control tyre, it can't suit all bikes in all circumstances, particularly if it is changed mid-season. I may be mistaken, but I think conditions have been unusual this year also, with mostly cool conditions and no new tracks. Here they got both hot conditions and a new track surface. Stoner has always been great on the hard tyres, and I still don't think he has won many races on the softer tyres, and no dry races at all on the ducati that I can recall. J4rno said some time ago that stoner's mini-"slump" was due to he/his team not having worked out how to set-up for a change in the formulation of the control tyre, which they have now done. I am still interested to know if he has or can win on the softer tyre, medium or whatever they call it now.
I can't defend stoner's pre-race complaints about the track btw, which were ungracious and unnecessary even if proven correct. Motogp is in a parlous state in general, barely hangs on in the US at the best of times, the race is apparently under threat, and the organisers have tried hard and laid a new surface. It is difficult for a new track surface to be other than new, and with Indy's iconic position in motorsports history some respect for the place is in order anyway.
