Ermont,
You are correct. Byron teaches to first learn your form, so you can then tune up your bow properly and then find your point on. After that learn your gaps out to your point on. He is a stickler on keeping the same bow/arrow combinations so that your gaps become ingrained to where you eventually just focus on your spot and let the subconscious set the gap that you learned.
In his book he talks a little more about it, but you may start off around 50/50 spot and arrow tip but you are working towards NOT relying on your gap and placing almost all of your GI us on you spot. He states it clearly in bold letters that once the gaps are learned and comfortable to start relying more on your instinct, and that is "becoming the arrow"
