I like what John Carter wrote. Me.. I use components of all three methods: Instinctive, Gap and Point On. I find in practice walk up / walk down different ranges for individual arrows helps a great deal, as does stump shooting which is more realistic. If you can find any Field Archery Shoots in your area, this can help a great deal in getting use to long distance shooting.
For the record.. my hunting shots are never more than 30 yards.
Real basic.. if your form and accuracy are good, I have a mental note that I have kept from another website: “If the mind is astray, so will be your arrows”.
