A lot of information there llyod! a great deal of it I can easily agree is more than simply valid.
The buffallo account reminded me of what hunters thought concerning me hunting whitetail with a 50 cal flintlock pistol. They alledged it was shakey.... but like you, I waited for a 50 yard broadside shot, (loose comparison), and did the difficult thing enough to bring the deer home for dinner.
Ironically I also shot competition while my health allowed it, albeit a different discipine. I shot silhouette, and similar to your experience saw only limited things useful that could transfer to my outdoor and/or SD training. I seldom shoot offhand if I can help it.
I moved over to falling plates competition in the "carry gun" catagory offered at my gun club. In a pretty short time I developed skills I had believed I already pocessed, and my draw,fire, reaquire sights, and SUCCESSFULLY knock down all the plates faster than a Hollywood gunslinger came to pass. (I thought less than four seconds wasnt too shabby for a sick old man anyway)
My other rangetime is just hunting practice. I kind of subcribe to practice makes perfect, and regularly using my hunting guns seems to help me. Like I said, I avoid offhand if I can help it.
Always enjoy your input on pretty much everything lloyd, looking forward to next time.
