Just because of the energy stored, I do the Manufacturers (Barnett) recommendation of 4 hours, with a half hour let-off/relax. I Got a crap bolt in the bag and do it during my lunchtime wizztime stretch time at midday.
Yes, I am not locked and loaded for a bit, and could miss a chance for a brute, but just don't like that kind of energy near my pretty face, and me shirking on recommended precautions!
“There is Truth in the Old Saying, That if you make yourself a Sheep, the Wolves will eat you.”
Benjamin Franklin, 1773
