Ok found the WSOP PDF that gives the load down.
WSOP Mega Satellites
Essentially multiple different levels of buy-ins. Final total prize pool determines how many certificates/tickets or "lammers" that are awarded. A $5k lammer is good for to buy into a $5k tournament. 2 $5k lammers will allow you to buy-into the $10k WSOP ME.
Doesn't seem to talk about the payout tho. For the $575 satellite, if the prize pool is say over $15k, does that mean the first 3 finishers each get a $5k lammer? Confusing part is that it says $5k or $10k will be paid out. Huh?
