Don't worry about some jerk who shoots his own hangers to get a higher hit percentage and ranking!
If your hit percentage is an honestly achieved one, and you feel a need to rate yourself, I would submit the following rankings:
<2.5% Below Average
2.5 - 5% Average
5 - 8% Above Average
8 - 12% Excellent
>12% Expert

This is just a guess...it would be interesting to do a survey of hit percetages. I think the largest group of pilots will be between 2.5 and 5%.

P.S. It occurs to me one must consider this, though: An effective pilot might shoot at a lot more aircraft, taking shots that are a low percentage of hits. But this will pay off in more kills and assists than the pilot who just takes "sure" shots. So, always look at the number of assists compared to the number of kills.
