I said "Advanced". Not because I think I am all that, but by comparing how I perform at local matches that test basic pistol skills. I'm not always winning, but I am in the top tier. Compared to the best shooters in the state, I may rank halfway down the list. With that said, on a national level, when compared to the freaks of nature in the shooting world (read Jerry Miculek), I am intermediate at best.
However, If you look at those who regularly shoot IDPA, USPSA, are on a SWAT team, have advanced military training (above simple rifle quals), etc. this is a relatively small portion of the total gun owners. It would be easy to classify all these people as advanced since their shooting has gone far beyond standing straight in front of a target at 7 yards punching holes in paper.
If "pistol skills" include such things as muzzle awareness and other safety aspects, again compared to the general public, I would consider myself advanced.
