I'd bow to the sport's scientist in terms of information regarding this particular aspect.
Jim's expertise is in walking, with I suspect a bit of knowledge in middle/long distance running where standing starts are used.
He may have an opinion.
My experience is more with crouch and block starting where the drive would come more off the lead block leg.
One thing I will say is that it's probably not a case of 'one size fits all'.
Body structure, height, weight and different rates of power and strength, and most importantly, reaction time are all variables.
I was a decathlete and an average sprinter. I trained a bit with the throwers and was asked by the coach of one athlete who was very highly ranked in the Shot at State level to run a time trial with him. I think the distance was about 40 metres.
I thought this will be a bit of fun, but at the start he left me for dead.
His acceleration over the first 15 to 20 metres was phenomenal.
It was the power and strength in his legs.
I managed to reel him in before the end but that acceleration was pretty impressive.
