10 gpp?

It has only 50% to do with draw weight. The other 50% is draw length. A 45@26 as you mentioned is different than a 45@28. Both bows cannot compare equally shooting a 450 grain arrow. Its impossible. A shorter draw length is at a power storage disadvantage and needs a  lighter weigjt arrow proportional to the bow of a longer draw. A 30" draw stores more at 45#than a 28 and a 26. Imagine the difference in performance of a 26 and 30 inch draw all other things being equal. The arrows must be of differnt weight.

That is what I am saying as well. 

Assuming a 28 inch draw and a 50#@28" bow:
29" arrow, 500 grain with 50lb bow = 10gpp.  On a short draw of 3 inches (7.5 lbs loss for a total of 42.5lbs drawn) the arrow would be too long and too heavy, weighing in at about 12gpp.

Using that draw length of 26" you would want a 27" arrow weighing roughly 425 grains for 10gpp.

We are both saying the same thing it seems. 

joachimM:
And using a standard arrow weight relative to draw weight allows you to objectively compare the performance of different bows.

For Gf recurves 9 gpp is typically used, for compounds it’s 5 gpp
