How is it that Archery has such strange measurement systems. Riser length is a physical measurement from limb bolt to limb bolt center and then add 5" Why do they do that? Why not just say its a 20" riser because one can actually measure 20 inches, instead of adding 5 inches to make the number bigger?
Like with draw length. Measure the string at full draw to throat of the grip and the add 1-3/4 inches
Or string length is the bow length minus 3 inches.
Its just crazy.
