If I understand correctly, you are saying that if you know the reaction level required to get a response at any given time, you can then select a lure with that score. I think the idea has merit. Specific fishing conditions, (time of year, water temp. and clarity, etc.) according to conventional wisdom, call for lures that would fall within a fairly tight range on your index. You could then say under these conditions a lure within this range, 10-14 for example, would be a good place to start. As RoLo said, quantifying the stimulus of any lure, as well as determining the number needed to produce a strike is the real challenge.
I like the idea, and think you could build a fishing "system" on it. Keep at it and I'll look for your book when it hits the presses. Maybe you could cut a deal with Glenn to market it here?
