PVDaddy --- did your read 3PO post -- I see the foot as you describe it - know how the pole moves - described some of the why earlier -- why is it none of the upper level coaches every talk about it in terms likes this - it would help if the terms were applied correctly or we had a cheat sheet to apply all of them. If you review/video enough vaults and are concerned with the path of the top hand (you are when you are looking at shortening of the chord and pole bend) - you would know there is not a circular movement of the top hand - and if you would plot the movement of the center point of the sail (part of the pole) you would also know it is not a circular movement -- thus no centripetal force -
The force the pole can generate is more aligned with the a chord line drawn from the pole tip in the box to the vaulters top hand -- and is not a centripetal force
Again if you read 3PO's post he outlines why a vaulter might drift and try and correct -- you are looking for something no one else has discovered -- not matter how many times you say how can you not see it - the only thing I can see is I do not agree with you opinion of what is happening.
