Draw Hand
The following is a baseline direction to begin with.
For dynamic archery, you do not apply an anchor point to be able to consistently strike accurately. You draw, then transfer the bows power into the shaft. To do this effectively you practice like its your life to attain good aim.
Your draw hand should pull first to the rough strength of power to transfer the weight of the shaft to the target desired. Wherever this draw ends, beyond the ear, into you chest, under your shoulder, it should leave your bow arm still well bent and ready to push the arrow into flight.
I find it detrimental to accuracy to push the bow into a full draw while your draw hand sitts relatively stationary. I focus on making my draw hand do most of the tension work. When aiming dynamically however an ease of analysis must be developed, which balances focus on what both hands are doing during the draw cycle.
Your draw hand is the foundational aimer; it determins trajectory and power needed. Aim with your draw hand. Don't try and aim with the bow hand after the loose. Remember that the bow is more like a rubber band sling shot than an atlatl. You dont aim with the sling hand after the shot, but you do follow through.
Your draw hand should receive no extra work beyond the direct draw back of the string from the stave; what I mean is, there should be no extra work from a twisting tourqe of the bow by the bow hand while your bow is drawn.
Coming to full draw is important as you want the limbs to do a good 98% of the work on the arrow. When you think you should use an "arrow spur" or other hand techniques to add power to the arrow, you shoot inaccurately, reducing potential power to the shaft, and easly ruining the trajectory of the arrow. However, you must still think to push the power into the arrow nock.
I use a slavic hold - middle and ring under the shaft, these pull - index, holds the shaft to the stave with a light pressure to the shaft; this is critical. With the Slavic hold, a light pressure from the index finger keeps the shaft near the stave and on the rest (whatever that may be). If the pressure is to heavy however this will impact the ability to achive consistency in accuracy. If the the pressure is so strong the shaft is bending, as an example. You must make it just light enough and no more.
If you find it hard to think about your index finger, slow down, and think about what you are doing.
Focus on making most of your shots come-back to a powerfull draw.
