Thats a great observation, Dave. Your idea hits on a point that many people (me too) tend to forget when working on form corrections ...alignment can affect results, and it doesn't just mean how you set your feet (stuff like arm/shoulder position, bow hand, bow limbs/string, finger angle on string, anchor place and angle, push-pull, etc., does matter). Getting all your "parts" set in a well-positioned angle to the target makes it easier to be repeatable and so its easier to shoot straight. In the early stages of inventing your own form, thinking about things like alignment is more important than when form has largely been built (i.e., when you have become comfortable with your basic style). When the basic style has been found, maintenance and fine-tuning are the goal and the issue of concentration becomes much more of a focus than body position aspects. Form practice will transform to mostly developing/tweaking concentration methods rather than for figuring out how to hold your body parts. "Working the bale" up close and with eyes closed helps groove the physical aspects of form for new shooters...and for experienced shooters who may be experiencing a slump or having trouble with some aspect of physical form. But, for those who have been shooting awhile and already have figured out/dialed in their basic form, the most difficult (elusive) point of practice will be the concentration part. And for that (somewhat paradoxically) its best to consciously forget about things like alignment, eyes-closed practice, release, and all the other physical components of shooting the bow. The focus becomes an effort to practice the sight picture...what you see, and what subconciously needs to happen to make the arrow hit 'right there'. Interestingly, I think its at that point, where concentration supercedes body part orientation as the prime directive, that many of the finer points of physical form become much easier to assess and correct. Hard to explain, but experienced shooters probably know what I mean.
Dave, you get an "A" in my book for noticing a good point about how body alignment can make a big difference, and an "A+" for having the forethought to actually consider how it matters in the scheme of things. Instinctive shooting may be simple in concept, but in application its better to be a thinker than to just "pull'er back and let'er rip".
