Ok, THAT' S IT!!! I' ve had it. I' m doing some experiments.
I was in the same situation Wed in 9 deg wx, but I was warm. I am convinced CONVINCED it is not muscular but that it is the cold limbs take more energy to bend. I swear that bow was pulling at least 10 lbs harder.
I' m going to measure my Altitude now, and then put it outside where it is 4 degrees. Then I will measure it again. I' ll post back in an hour.
