I still do #3 and make sure I do not draw off line high or low past my anchor.........that's the key for me. Sometimes I have a tendency to draw back under my anchor, then as I settle in I also have to bring my anchor up slightly and I would shoot a touch high because I would relax and shoot before I completely settled in.

As long as I draw back smoothly with a good deep hook on the string and stay on that correct plane before I settle in I'm money. There are a couple subtle things going on as well as I hit anchor too. I make sure that my elbow has come around and my back is squeezed firmly into the shot just as I release which prevents collapsing.
I definitely take about 1-2 seconds of hold to clear the sight picture just before release too.

So in a nutshell, I see the shot (hard to explain but it sets everything to happen next) , draw with the arrow closely on it's intended path while watching the spot I want to hit. I draw to and slightly beyond my anchor making sure to stay on the correct plane (most important for me). I settle in to anchor and at the same time really transfer the holding weight to as much back tension as I can in a short time before I clear the sight picture and release.

2 things that will get me off target a bit high or low are not drawing to my anchor but UNDER it, and looking back to the tip of my arrow at full draw to see it's position.......this takes up valuable holding time where I should be looking at the spot I want to hit and adds a second or 2 to the shot progression because I then have to re-find the spot I want to hit. Also Igenerally have to re-establish back tension and fully clear the sight pictureall of which adds up toabout a 50/50 chance the arrow is going to find exactly where I want it to hit.

I am FAR more consistent drawing right to my anchor plane, but slightly beyond to make sure I'm not short drawing, all the while NOT taking my eyes off the spot I want to hit.

Also make sure as you set the shot you have picked a spot BEFORE you draw. I know this sounds elementary but sometimes I find myself trying to pick a spot WHILE I AM AT FULL DRAW and there is too much else going on that the mind is trying to process and it's hard to focus.
