The critical factors in understanding the consequences of making a change in an action parameter is to understand the leverage of the system in it's entirety.

Submitted to David Stanwood's formula permits you to determine the actual strike ratio which is the overall leverage of the action. If your action is currently over leveraged then moving the capstan makes sense but if the action is currently well leveraged then you will have an under leveraged action which is as bad to an over leveraged one. Before to start fixing something not broken you need to know fully what you are doing by understanding Stanwood's system. Once you understand this system you can analyze any action and know where the problems lie. Newton
