The flaw in the method...

The technique is dependent on the left arrow and the right arrow boundary points being within the -20 to +20 range. You're probably SOL with this method if you have lenses that require AF fine tune values above say -15 or + 15.

I think you might still be good - it's just that for the purposes of the midpoint calculation one end of the range will be fixed at -20 or +20, giving you a little less wiggle room for midpoint accuracy.

Sure. Just saying that there is a limitation to the method. I have a couple of lenses that require a number round -18. I'll have to see how this method treats them.
