Stacking can become an issue for individuals with longer draw lengths, 30+ inches, but the majority of trad shootersfall under 29" and it's typically not an issue. Unless it's a really short design. The 28" draw is a standard used by the industry that fits the majority of shooters. Some individualsof course will be shorter and some will be a little longer, but the majority fall around that mark. With a bow marked for a 28" draw length, you can add or subtract about2-3# to/from the draw weight for every inch you are under or over the marked draw length. Example, if a bow is marked 50#@28", it'll pull around the 47/48# mark at 27" and 52/53# mark at 29". As mentioned above, having a consistant anchor and draw lengthisimportant to consistantshooting accuracy.
