My own sequence goes.
Aquire target,this is the begining of aiming and is maintained throught the shot.
Correct stance,
Grip the bow,
nock arrow,
grip string,
Draw,
anchour,
Settle,
Release/follow through.
That's the base of it,but I can spend a lot of time breaking any one of those down into another long list all of it's own.
I don't normaly use this in any place other than my back yard.
During both competition and some times while hunting I will do a mental check through before I decide to take my shot,but really these steps are used to ingrain the shot sequence to a subconcious level so that it becomes automatic and I don't need to think it through.
The day comes that I step up to the line and try to go through all those steps in an effort to actualy shoot better there an then,will be the day that I know for sure that near on 40 years of practice has been a waste of time.
Distraction,,,,is a mental issue.
The shot sequence is a physical issue.
Trying to use the physical to control the mental,,,is not going to work,,it has to be the other way round.
Distraction needs a mental fix.
