I do take comfort in the mathematical explanation for my fumblings around landing a steelhead on a fly. The steelhead is the fish of a thousand casts so FishPerCast = .001. Factor out dirtbag side-drifting, plugging, spoons and bait fishing, and your talking more like the fish of 5000 casts; FPC = .0002, Now factor in the fact that I haunt a 'fly fishing only' area almost that disallows weighted flies, multiple flies, barbed hooks and bobbers. Things are more like 1 in 10000 so FPC = .0001. I might get that made up into a cool logo and put it on my fishing hat.
