Aiming the shaft: the most important principle in archery
To some it may seem obvious, but - the most important step in archery, regardless the type, past or mosdern, regardless what he or she says is correct archery, regardless the bow, or hand technique you do or don't apply the shaft will be set into a streight (it can arch or curve slighly - the more so however, the weaker the impact) trajectory and a direct force is applied to the nock, that will follow the length of string draw to bow brace. The nock must meet rough to the point in space where the tip of the arrow was at draw.
Simply put, regardless of what technique you apply, khatra or move to the side, or both, or none, your goal as an archer is to direct the shaft into a trajectory to its mark and propelling it by a force to the nock (these hand manipulated mechanics are calibrated faster and increasingly subconsciously, through much practice and they are judged based on the weight of your string draw and shaft).
Focus on the truth just stated while confused at practice in dynamic archery. When you dispell with peeps and shaft, one eye aiming - remember this truth.
Just focus on mastering the trajectory, applying right amount of thrust, and a steady and accurate follow through when the string is released.
As a person learning dynamic archery, your greatest enemy is lack of disapline.
