question on how informal rush works

I have a question about informal rush. Now that bids are out and the houses can start informal , can they offer spots to as many informal pledges as they want? I’m getting different information. Someone told me houses who meet quota can only give out spots to fill spots that drop. Other people are telling me houses can give out spots as they see fit to fill their house.

With numbers so low I’m wondering if they will want to have more pledges to spread out costs better to fill the houses etc.

This is not a bash on any house nor an argument about process. I’m curious about numbers to assess chances of getting an informal bid. If there are only spots opening to fill drops from houses who met quota, that’s not a lot of openings.
