Drawing against made Badugi

[ActionFreak]

I am trying to get an estimate of what pot odds one would need to draw against a made Badugi.

For example, in a big multi-way pot with A25. We know how many cards that we discarded and that one villian is pat so he has one of the suit that we need and three that we don't.

There are 12 of our suit left. How would we discount the outs that may or may not be good?

Can we really even start with 12 outs if there are several other people drawing one and there is 3/4 of a chance that they have one of our outs?
