Most of the smaller ones are lurkers, and don’t take much active role in discussions/surveys and therefore, you only see the large guys here, who openly tell how huge they are.
Therefore the average here is probably equal to normal average.
You could be right about the smaller/bigger ones, Many will probably be afraid of posting pictures and stats if they consider them self small, But they could still be posting in threads and polls. Also this is a place where people are accepted as they are, No matter what size they are. The guys here are very supportive and helpful.
Well, If I had a natural NBP 8x6”, I would probably never have found or joined this forum, Or used sooo many hours to make it bigger, Or would I :-k
