Youwant to tunefor a specific goal of getting broadheads and field points to hit together, regardless of whetheryou get the very best accuracy possible with either. I guess from that perspective a bow could be called a perfectly when you achieve that goal.

Then you changed your goal and wanted the best possibleaccuracy with your broadheads, so you fine tuned the bow for broadheads. But thatfine tuning wound up'detuning' the bow it from shooting field points and broadheads to the same POI.

You could then turn around and decide you want to shoot field points in a tournament with that bow, so you fine tune it for top accuracy with field points. Then you'd be 'detuning' it from shooting broadheads perfectly, but it would be fine tuned to fit the new goal.

I prefer to think I'm fine tuning a bow to fit the job at hand. I've never really given the slightest thought that I was detuning it from doing another job. Detuning... Kinda silly to think that way, if you ask me.
