9.48 in 500 years?

We’d have to look to conditions as you suspect, but there is a significant drop in times in the 90s attributable to improved surfaces. Now anyone able to look at R/Ts from major champs to see a shift?

Gideon B. Arial hypothesized in the late '70’s that .: 9.60 would be the limit of the human body mechanically, that to exert the forces and limb velocites necesary to exceed this would crack bones and pull tendon from connection points.

Any thoughts?

Gentlemen:

What part would improved footwear be in relation to faster surfaces?

1.79/1.04/0.88/0.86/0.81/0.82/0.81/0.80/0.83/0.84 - with Golden Slippers!

10.34 - 1.98/1.09/0.96/0.92/0.91/0.89/0.89/0.89/0.90/0.91 - with Platinum Slippers!

Dazed
Any speculation into limits is doomed to failure and ,as we see people moving towards 9.60 in the near term, what will Arion say next?
