Action ratio and knuckle distance

[Farrell]

Stanwood's equations of balance would tell you that. Are you familiar with David Stanwood's work?

    How do you figure out the change that would occur in ACTION RATIO (AR) if everything remains constant (strike weight, front weight,wippen balance weight, and balance weight) except the knuckle is changed from 16.2 mm to 17mm, on paper, without actually trying it out on the action?
