The P4LE version is for people who want to distribute a Michael 2 P4 cr2. It's got nothing, really, to do with Michael 2 - it is, as you say, the P4 version. Personally, I think using a CR2 for that is daft: the only morphs you'd want to use on the P4 figure are the head morphs, and it's way easier to distribute them as a .fc2 file. Takes up less space, too. Michael 2 characters can only be distributed as .pz2 files: MAT and MOR poses. Otherwise, like with Victoria, you have to use the Mike 1 CR2
