How often do you see the same players?

I'm multi-tabling the Stars $27s and the most I've seen any one other player is in ~2% of my games, and even adding up all the other guys who I know are multi-tabling it seems like they only show up on average once every 2-4 games or so.

For some reason, I would have guessed those numbers would be higher. Anyone else want to share what they're seeing? I rarely play at Party right now and am curious if folks see a different number of familiar faces there (or elsewhere), as well.
