I keep lists of tourneys on a number of different sites. Just took a look at my iPoker list & thing is, they don't always run at the same time each day (some of them do, but they change it up a bit). ie. on weekdays at 14:30(est) there's a $11 $5,000GP (sometimes it's $6,000GP), but on the weekend it runs at 13:30.
There's another $10 freezeout each day at 17:00(est), $2,000GP.
There's a $5 freezeout each day at 15:00, $4,000GP (sometimes it's $3,500).
There's a $5r/a $10,000guar. each day at 16:00(est). (~1hr. earlier there's a $10r/a $18k-$20k guar.).
There's also a couple of $1 buyins each day... the freezeout used to have 3,000chip stacks to start (but just checked the lobby & they've recently changed it to 1,500 ... sigh). It runs each day at ~15:00(est).. maybe 14:00? An hour later there's a $1r/a $1,500guar. (these two tourneys are called DailyDollar & DailyDollarRebuy).
What time of day are you looking at playing? (earlier in the day there's a few more... ie. $3r/a $4,000guar. at 11:30est). There's also a bunch of $5 freezeouts, with guar's ranging from ~ $1,250 to $4,000. They run approx. each hour (sometimes everyother hour). Players are real bad in those $5 freezeouts but you don't get alot of chips to start out with (1,500). The $10's typically start you out with 2,000chips (but the one at 2:30pm sometimes starts you with 3,000chips).
For low buyin, they've got two deepstacked tourneys at 5:45pm & 7pm ($25 & $30 buyins), where you get 6,000chip starting stacks! There's approx. 100 entrants in these each day (sometimes 120).
Later in the day (after 7pm est) the site really slows down.
Also, during busy hours you can get into some 30man Sng's too (later in the day these don't even fill up... but earlier on you can probably get in 4 or 5 at a time). Structure is pretty fast compared to say FTP or STARS 27 man reg. speed SNG.. but players are shittier too. They've got $5's & $10's (I think there might be $2's as well, but I believe the structure is even faster in those ones for some reason)
