Yeah, but the reason he can't use his speed is that he is/was lacking endurance. The 11.3 is a significant number, no matter what the pace of the 800m was: it doesn't show that this race would have been THE race, but it DOES show, that the 46.0-speed was still there. Surprised your calculator doesn't tell you that. Helsinki was on the 5th of July. Combine that with the endurance to run 3:31 of the most ridiculous pace ever, and you got the tools to attack the record. In Oslo (11th)he could have challenged his time, no reason to think otherwise. And the track there is for certain better known to be fast than the track in Firenze.
