Yep......................from my experience trying to put math to wood lures does not work............there are far too many variables. Add weight, hooks, and clearcoat and test. Take notes, repeat. Sometimes you will get lucky and the first couple of tests will work out great, other times you run a dozen tests and the lure still doesn't work very well. I have entire notebooks filled with notes, trace the lure, note the lure thickness, wood type, hook placement, weight placement, test, then write down results. After running dozens of tests you will start to see patterns that will level the learning curve.
