Are your patterns spread out horizontal?
When I try to extend my draw length, the arrows go left and right. Why? Because trying to expand that extra inch is kinda forced. The expansion I feel going longer is fake, and the pattern shows it.
I am 5' 10.5", and I draw 25.25, flat NA bend in handle weapon system. A lighter bow will show 26", but the heavier draw compacts me (I went through the draw length worry process a few years back. I called it the 'draw length wars', all fighting in my mind. Like my camouflage war, my broadhead war, my fletching size war, I finally settled into what works for me).
One guy on other sites said he screwed up his shooting bad when the internet came out, and he quit reading shooting posts for two years, just to get his groove back; he is well known, I assume.
So, I would do what the others say. Shoot that 26" style. If it goes back to 24" 25", as long as it is consistent, all good. Hunt with what works, and like the old Ryman Cat said once, hunt the shot. Meaning, look for where your form and range intersects deer. Honestly, people worry too much about inches, like feathers, draw length, etc, when most of us primitive archers make weapons of mediocre speed and so we are most likely in the typical 20 yards-and-in club of hunters. (not all of us, so do not flame me).
Hope this helps.
Best book I read, by the way, Jay Kidwell's Instinctive Archery Insights. Know thy trajectory.
