Is it common for your draw to change as your form evolves or develops?
I ask as I found that my draw has gone from a measured 28" to 29" in the last month or so.
In that time my form has evolved a bit, with a more open hand/higher wrist, elbow better in line with my bow arm, and primarily back muscle at full draw, rather than shoulders/biceps. This is much more comfortable and my shooting has become more consistent.
A couple disadvantages are that I had to buy a couple dozen new shafts and build 30" arrows and have about 3.5 dozen 29" arrows I can only shoot with target points.
Also found I was drawing 55lbs with my 51lbs 58" limbs which was a touch too much. Swapped back to my original 60" 48lbs @ 28" which are 51lbs at 29", and everything is cool.
Also had to get ahold of Tim at Kota Bows and Greg at G&M to have the my custom Swift and Hunter 56 made 50lbs@28" rather than 52lbs if it isn't too late in the game...
