I'd agree that you are doing much better than average.
From being on the ranges all over the country with some of the best shooters, including some of the top dogs from the AMU, internet feats of 1911s into 1" at 25 yards, and M4s into 1MOA at 100 yards are mostly outliers at best.
Offhand, holding an 8" paper plate for 5 shots with a hunting grade rifle at 100 yards is beyond the capabilities of most shooters. There are few people that can hold better than 3MOA offhand. Use a 1MOA rifle, you are going to average out at about 4MOA...which is going to put a person as one of the better shots around.
