I see your point, but I don’t think that it is a fair comparison. Ben had shorter levers so in theory she should have an advantage from 0-60m.
Secondly, Ben and Carl trained under different coaches and although I don’t know all the particulars of SMTC, I’m pretty sure Carl’s coach did not focus on 30m sprints, resisted sprints ( isorbic exerciser) and EFE drills as much as the late Charlie Francis.
