Len,Kevin,
From the description of Jeff' s conversations with Dave Cousins I think its safe to say that it was meant " in fun" apparently Dave is a shooter who is shall we say " A Cookie Cruncher" and I doubt he meant anything offensive by it. He had Jeff laughing the entire time. So Kevin I think your instincts are probably right on that front.
In any event I find it hard to dismiss this little bit of insight.........if we strive for the utmost in accuracy that our set-ups can give us ,our margin for error decreases. I think any animal we shoot at deserves our best attempt at " Vegas Spot Accuracy" (no offense intended by that comment Len)
If it helps tuning issues , broadhead / arrow flight , nock travel or whathaveyou even a little bit, IMO its worth the extra couple of minutes to set it up.
