I'd say too late, that generally fills up as does the LR match. wouldn't hurt to email them (info@peacemakernational.com) and ask to be put on a wait list.
they have DMR events listed on their website thru December. I just clicked on December's and it looks like you can register now, so prob the same for the ones before it.
they do require payment upon registration and it's nonrefundable, so there is a risk for doing it way early. of course, it fills up fast so you can't wait til last minute either.
