Puzzeler from Seattle

[Joseph Alkana]

Well, I don't have any method that solves this problem easily. If an action 
has poor geometry to begin with, many of the key arc, pivot points and 
resultant weighting and friction consequences would have to be refined, I 
would think, almost empirically. I believe Stanwood's method has some 
avenues for resolution, but I have no first hand knowledge if action spread 
is addressed.
