The prize pool contains 2 packs per player, you can distribute them however you like.
Sadly I see a lot of stores making really top heavy prize distributions, where for 20 players (40packs) they may only give out packs to the top 3 or 4 players. I prefer, given the more casual nature of a pre-release and the excitement of new sets, to push prizes down to at least the top 50%.
But as Wizards -gives you- 2 packs for every 1 pre-release kit they allocate you, putting fewer than 2 packs into the prize pool for every 1 person in your event is pretty blatantly misusing their prize support.
