I commiserated with the athlete as you should be the first one to real realize that you've "missed the brush", not the last or worse, contend that you indeed had hit the brush!
After a few questions on my part it seemed to me that "eye dominance" was a factor in the dilemma, perhaps the out-and-out cause of the disconnect between player & skip. I hoped the athlete would contact me with the success or lack thereof of the advice I offered. What follows is that feedback and my response. For privacy purposes, I'll call her "Sally" (what ever happened to that name?).
NB - if you've not done so, please go to my previous post of 10/22/13 entitled "Quiet Eye -A Home Assignment". I'll be drawing conclusions on the amazing research conducted by Dr. Joan Vickers of the University of Calgary plus what actor Alan Alda (of TV's M*A*S*H fame) learned at the University of Aizona. It will change how you mentally prepare to execute a curling shot. It certainly changed, in a profound way, the approach I take in assisting curlers with the only challenge that really counts, making curling shots!
