what am I doing wrong

[srp71]

Well I am layed up with a busted leg for almost two months now. So week or so ago I decide to start shooting my bow again "just in case I can salvage some of the season. So I set up my chair on the deck,I figure it would be good to practice sitting and shooting from a blind anyway. So first two nights I shoot normal, or as close to normal as I am.Then for what ever reason I start shooting to the right 6-8 inches until to nite I missed completely with three arrows,one more barely hit the target and the other two were about 8" off center to the right.Horizontal plane is good.Now my buddy was over a few days ago and told him what was happening and he put 6 dead center and a couple inches high.So I doubt its the bow but it is me.What am I doing wrong all of a sudden?As far as I can tell I am doing everything the same,Except siiting instead of standing.

Maybe the release arm is not straight in youre sitting position

Sounds like hand torque could be the problem
