Arne, thanks for the input. I really appreciate it.
My typical practice regimen is about 15 to 20 arrows blank bale shooting before I go to work every morning, and again when I get home from work. I can get 14 yards in my basement during the winter, so I throw in some "distance" shooting at the end of every day. (an additional 10 arrows maybe)
On the anchor, I've been struggling with this for 2 years. As soon as I knew my arrow would hit its mark, my brain would force me to release the string. I've shot really well like this for a long time, but releasing 0.5" - 3" in front of my anchor on short shots and hitting anchor on long shots was getting frutrating. My arrow hit its mark most of the time out to 25 yards, but I'd get random flyers that just drove me nuts knowing that an inconsistent anchor and draw length was the cause, and I just couldn't break the mental barrier to fix it.
So about 3 weeks ago I introduced a "second anchor" into the mix. As soon as the base of my thumb knuckle drops in over the back of my jaw bone, the arrow is on its way. This guarantees that my middle string finger at a minimum touches the corner of my mouth prior to releasing. The short draw or premature release syndrom went away almost instantly.
For the first time in 2 years, I have complete control of my shot no matter the distance to the target. It is quite a liberating feeling.
One thing that I've introduced into my practice regimen is drawing back to anchor, really burying in, and olding for 10 seconds. Let down and repeat. On the third iteration, I shoot the arrow after the 10 second hold. (Larry Yein suggestion from MBB3)
This works great on Blank Bale, but as soon as I introduce a target, or my eye picks something to hit, I pass through my anchor everytime. I'm very comfortable shooting in a fluid hill style draw / release, but wonder where my accuracy could go if I settled in a bit prior to pulling through the shot.
Any practice routines that you may suggest to further help me try settling into anchor prior to pulling through the shot?
On the "head slouch", I will try to implement that today in my evening shooting session. It makes sense to me. If I keep my spine in line, my draw length will be much more consistent.
Thanks for the input. Anyone else see anything?
