I've been shooting for a couple of months using instinctive aiming. I haven't seen any improvement for a few weeks, so today I tried gap shooting. I was all over the place initially, but by the end of my shooting session I cut my group size in half. I also quit getting the occasional wild shot I usually have.

I'm going to stick with gap shooting for now. Hopefully today wasn't a fluke. I'll probably still use instinctive aiming for bow fishing.
