Yes it is possible for me anyway. There is a point where I rotate my shoulder past alignment with the back, or I use my arm/shoulder to pull out and back. I don't know exactly which or if it is a combination. I learned my limit by concentrating only on the back and really getting the arm and hand relaxed. Then I fine tuned by paying attention to the release, follow-through, and arrow flight. If I get kind of a pluck I know I have gone past because I am not releasing in line with good follow through going straight back, and I get a weak direction arrow just like short drawings and plucking.
After all my form changes I was over drawings by as much as ½” for a little while. Then I settled back in to a little shorter draw. I am still playing with the last ¼” trying to settle, but most times I just shoot and don’t work about it.
You will feel the extra weight with the longer draw. Plus if you are really using your back and were not before, you will feel that a lot. If you feel tired in the arm and shoulder, I would guess you are overdrawing and pulling out and around with you arm/shoulder.
