If I understand your post correctly, you are an instinctive shooter who is aware of the arrow. Some would dispute that this is instinctive, but since I do the same thing, as taught by Rick Welch, I would agree that we are shooting instinctively. An instinctive shooter does not want to make conscious adjustments to aim, like a gap shooter would, anymore than a baseball player or a basketball player would want to make conscious adjustments to his throw or shot in the moments before he makes it. So what you want are ways to adjust your POI without consciously making aiming adjustments. This is a valid desire, and one shared by many good and great shooters.
First, make sure your form is correct. There is a lot of pressure on your bow arm during the draw, and incorrect alignment can cause the bow arm to rise when the bow is drawn. Make sure you have a strong bow arm. Do exercises or practice drawing and holding the bow slowly to build up your upper body strength.
Do not ever focus on the point of the arrow. If you are aware of the point of the arrow while you are holding at full draw, it is easy to let your focus accidentally shift to the arrow point. This will cause a high miss. The arrow point should be out of focus in your peripheral vision at all times.
If you're doing everything else correctly and still miss high, then make mechanical adjustments to lower the POI. You can use a heavier arrow. You can raise your nock point. Don't worry if you have to raise it higher than tuning would indicate is optimal. The feathers will quickly correct the nock high, and the arrow will fly true.
I just recently realized that raising the nock point only works if you're truly shooting instinctively. If you're cheating and using the arrow point to aim, consciously or not, you will just move the arrow point up to compensate for the higher nock point, with the result that you'll be shooting a poorly tuned arrow and still miss high. There is nothing wrong with “instincti-gap” aiming, but in that case you would want to adjust the position of your arrow point consciously, as Arne suggests.
