Bungie calling out numbers for Halo Reach, saying they are WAY off.

If I play with a friend on my xbox 360 does that count as two unique users?  And yeah people are spending a lot of time online thx to Daily weekly challenges... Halo 3 looks now kind of boring without those challenges and I am sure their are people here who are addicted to it like me;
