Tom, while some folks might consider what you did coaching, I see it as growing the sport. You did it off the clock and it is was done to help a new shooter, potenially reducing his frustation level and increasing his enjoyment level.
I had a Chief tell me one time "You are always training your replacement, no matter where you're at. While this elderly gentleman is probably not your replacement, doing the same thing with younger shooters does accomplish that goal.
