Minor stupid question out of curiousity

X of Y Connected (Z in swarm)

I was just wondering, how exactly utorrent determines the Y and Z. I mean what the difference is. For example, if it says something like 2 of 5 connected(3 in swarm) how is it that the swarm is less than the 5? I mean if I can connect to a possible 5 people, shouldn't the swarm say 5 as well?

I'm guessing this has something do with DHT maybe?

(3 in swarm) is how many the tracker reported were there in the last announce.

I see. What I'm asking is where the 2 that aren't in swarm but are apparently 'there' come from. Is that DHT's doing?

I know it's not just outdated data or something like that since I announced again to make sure.

And oppositely, what does the reverse mean when it says something like

2 of 3 connected (5 in swarm)

What is it that stops the client from counting 2 of those 5 as connectible?

This isn't really important, per se. It's just been bugging me since I don't really know how this stuff works and I'm a curious fellow. Thanks for humoring me

Incoming connections will do it. Not necessarily DHT related.

Tracker updates only happen every so often, so data from the tracker is out of date.
