Not as simple as that because we can know how Ben arranged his program but can’t be certain of all the program details of the others. As well, the tracks are certainly faster now than they were in Ben’s time. The change occured in 1991 with startling changes in performances, mostly centered around improvements over the first 30m. Ben’s clearly superior accel over all contemporary rivals would only place him near the front now, even though his top speed and 60m overall times still hold up.
Greater energy losses over the early race stages cost over the final segments. This can be seen by the fact that, while the 60s remained relatively close together in Ben’s indoor season and outdoor splits, the 100m times required a major taper to maximise.
I would suspect that was true for most contemporaries because whatever Ben’s times along the way, he was completely dominant throughout a three year period.
