Simple.
Hold the bow up against a nice straight wall, beam etc with the tips touching the wall, see how many fingers you can get between the grip and the wall. 1 is great. 2 is fine. 3 is getting a bit poor, but can still be a great bow.
Of course on a deflex reflex design that may be just right.
If the tips won't touch the wall you have some reflex or the bow is round the wrong way

The trick to making bows that exactly meet spec' and timescale is to write 'em after you've finished the bow
