The rules you described may be a requirement for the range insurance company.
You mentioned drawing from a holster.......
The difference between me and that man is that I know what I'm doing. I've been drawing from the holster for many years--since the late 1970's--and I have never shot myself.
I remember the first time I did it was at an IPSC style shoot. I had just bought a 6" Colt Trooper Mk III, and either a Bianchi or Safariland swivel holster for it. Two silhouette targets were at 2 and 3 meters, and at the buzzer, one shot went into each target and the gun would be re-holstered, and it would be repeated. I know I did abysmally in the other stages, but the range guy said that I was pretty good at drawing from the holster.
