They were low but remember she was talking to the camera with only being able to view the miss in her 10x scope. She hadn't seen the zoomed-in video at that point. I've shot paintballs with my Kimber 84G and a 10-20x scope at 100 yards -- easy from a rest but freehand standing is a whole other problem.
The one issue I have with her videos is safety. She's sweeping that muzzle all over the place and she should have been treating the rifle as if it still had a round in the chamber when the magazine fell out. Maybe I just spent too much time with training Scouts but I cringed as I was watching.
She's got skills and she's easy to look at. The first point is more important but the second is still a bonus.
