I too am hard of hearing myself. I made the above statements because of seeing it happen with me own peepers. I am NOT saying that a hearing impaired shooter will prone to doing this. I am just stating what I have experienced. You are correct as to not having been at a match with a hearing impaired shooter.
To reiterate if a shooter with hearing has done it it is very possible for a hearing impaired shooter to do it also. My apologies if I insinuated that only a hearing impaired shooters would sweep the crowd because of being taped on the shoulder.
No problem and no hurt feelings haha its easy to misread or misunderstand a post on the internet.
