If you shoot out a hole in the paper, the most valid assumption will be that all of your shots passed through that hole.

In the 1912 Olympics George Smith Patton Jr, participating on the US Pentathalon Team fired a one hole group on his target, and was scored with one miss, costing him the gold medal.

Since then the Olympics have made provisions for situations like that.

CHL qualifications are not Olympics.

I would say your friend is wrong. If you put all your shots in one hole, they should all be scored, and the ROs are pretty likely to notice how well you shoot.

Be as accurate as you can me, unless you are already a superb shot you won't have to worry about spreading your shots out.

My wife shot a perfect score on her requalification and nobody questioned whether her shots passed through a few holes or not, even though she made a couple of large ragged holes, she was obviously shooting that well. (Of course she was using what was then my XD9, which she then promptly decided was hers.)
