I've had the same epiphany, literally three days ago while in my treestand.
I worked since last January on shooting 3 under and saw what I perceived to be immediate progression in my shooting. I liked it , stuck with it, killed a deer early November with it.
For some reason though, while getting situated the other day I took a few practice draws down my shooting windows. For some reason I could not get comfortable, could not get a repeated anchor, and my sight picture seemed very out of focus...if that makes sense.
For giggles, I wrapped my finger overtop the nock and drew back the bow again. This time, my forefinger found a solid anchor on my boney ridge right below my eye and my sight picture cleared right up. It just seemed natural. I quivered my broadhead arrow and grabbed my small game arrow and found a oak leaf ontop of the snow about 14yds away. I drew, anchored, paused briefly and let the arrow go...I ripped the leaf in half. The shot felt effortless. I grabbed my other small game arrow and found another leaf at between 20-25yds...well outside my set hunting range max. Repeated the shot process, and my arrow landed just under it, with one of my feathers pulling the leaf down partly into the snow.
I'm liking this. At least for now...who knows what I'll like in a few months.
