Dave, glad you found it helpful.
Couldn't come up with a jersey glove, so I grabbed a storm cloth glove I bought last year that is water/windproof. Not sure what it's made of, but it's really slick and form fitting
I had shot several shots earlier this am, same issue, impact was non-consistent, depending on hand placement. By non-consistent I should point out that group size was around 2.5" at 25 yards.
Slipped the glove on, went to pull arrow from target. Figured out real quick the glove was slick

Walked back to 25 yards (max I can shoot indoors where I'm set up), set high wrist, draw letting bow settle where it wants, anchor, NP is perfectly lined up, aim release. Pulled arrow, repeated.
Holy Crap, would have been a robin hood if I would've shot a second arrow. Proceeded to stack arrow after arrow into a nickel size spot. I'm still smiling like this
It was an amazing difference. Give this a shot if you don't already, I highly recommend it. Bow just settles into the same spot in my hand with no effort on my part. Made a big difference for me.
