Daryl,

What do you mean by maximum thrust?

Do you refer to the total thrust work or the max thrust force somewhere in the down swing?

I think you get max thrust force with a rather late random sweep release - if you time it such that the overtaking / release of accumulator #3 happens in the place of the down stroke where you have the most drive loading power - the place where you can really lean on the shaft - and that would probably while you still have the majority of the ground force throught the right foot and when the hands are in the region under the right shoulder.

I'm only speculation here so I may be wrong.
