Nick: Let's make this easier. Attached is a spread sheet and people are welcome to play around with it. It's not complicated to set up. I've used your definitions of the input and output arms. Independent variables are in yellow. The key question here is defining let-off as either a constant or a percentage of total dip. I've used your 25% of total dip figure. The particular data is from an action I'm working on. David Love www.davidlovepianos.com -------------- next part -------------- An HTML attachment was scrubbed...
