That's a tough one! I'd suggest it'd have to do who you're connected thru & the common connections they have. Particularly if you did a direct connect upon them. They share the same no. of certain files but I'[m sure if your browsed all of them you'd find they had different files. I'm sure another member/mod will have a better explanation. I have come across not too disimilar results for certain artists. 'Perhaps' because they're the most popular files. By the type of results (same connection type) it'd tend to suggest a browse or direct connect., right?

If that be the case & even if it's not, I wouldn't be too worried. I don't know whay it should be 11 though. Perhaps coincidence. Or perhaps as I suggested earlier similar tastes with similar choices. And the ones you're most easily connected thru. Particularly with your upld & dwnld habit.
