I am just starting out in Trad Instinctive shooting, but have shot compund for 20 + years. I been reading books and asking questions like crazy and what I found work best for me is to start from only about 5' from my bag target. I focus on the smallest spot on the target, draw, release. I did this for probably 300 - 400 shots and At only 5' i was able to get my groups down to about 3" or less, I then went out to 10' and started the same process again till my groups were consistently 4" or less. I just moved out to 15' feet. For me it becomes getting the feel for the right spot and just repeating the same thing over and over and over a couple hundred times, till it just becomes natural. Then I move out farther and do it again.
Each day when I go to shoot. I start out at 5', shoot 5 or 10 and then move out to 10' and then 15'. It will not be to long before I run out of room in my basement, but hopefully It will warm up outside soon and I can head out there.
Again I am new to this and from what I read and the advice I received. This worked best so far for me. Good luck
