I'll kick this thread again with my Deteriorated Eye Sight results today, after continuing a LOT of practice for the past few weeks. The IDPA range was vacant, so I used it to walk around and fire from varied distances -- this is draw and fire 3-5 round quick volleys, holster, move, draw, repeat -- moving from 7 yards to 15 yards, quick stance. 8" target. I had some flyers, and not great by any means, but it ain't standing in one place and taking slow aim. Slowly improving a bit, maybe....
