Think I figured it out..
Kind of funny the way the distance is measured in FT and YRDS but the
target size is always in CM Centimeters don't matter if it's International or Other.
That's the way they do it at the NFAA.
All the above is posted based upon NFAA documents, right or wrong I'm just
doing this based upon what the they put out on the internet.
My best guess is what I show here is true but take it upon yourself to verify.
