You don't have to think that way, just plug the result in and fit the required blade. I recall now the saying was something like hit high, fit high/hit low fit low - but no real need for it now as irons are generally only good for feck all (and target). I did a wee bit with them in the early days of my hunting, but in any sort of crap or inclement weather found them crap and soon moved on.
