Just to keep the specific issue up front, I am talking about the advocating of using a bent bow-arm to be part of a correct shooting form, period. Not a temporary adaptation to meet a difficult shooting situation in the field.

Should a person train to shoot the correct way and adjust/adapt from a correct method for a difficult shooting situation that occasionally occurs, or acquire a conditioned shooting form that is not the best shooting form for best and consistent accuracy, but might be handy in case the person faces a difficult shooting situation?
