The angled capstans, when turned up to accomodate wear in the action, will 
also increase the ratio.   Thus, with the expected lower friction and lighter 
hammers of a well used action, the ration will gradually increase to take 
advantage of the condition.   Perhaps, over the life of a set of action parts, the 
ratio would increase from say 5.8 to 6.0, mainly as a result of creating a 
shorter moment arm on the whippen.
