I guess I'm just kind of a skeptic and shy away from making any assumptions about the way adcoms might function. For all I know, they accept only 15 extremely strong candidates during the regular cycle (Oct-April), defer the vast majority, and then spend May-August carefully selecting the remaining ~21. That would certainly be one entirely reasonable way of doing things. Or, maybe they accept 36 outright and then wait to see who bails. I have no way of knowing. However, the fact that there are 22 people on the accepted students Facebook group is a pretty good clue that they've accepted around that many and probably a little more. Of course, the skeptic in me doesn't discount the possibility that anxious people floating around these forums might sign up for that group despite having not been accepted yet. But there's at least some objective info to suggest at least 22 have been outright accepted. Nothing suggests they've accepted 36 already, even if it may be true.
That being said, item #4 on this list (
https://www.aamc.org/students/applying/recommendations/62826/policies_admissionofficers.html) says that all schools must have accepted at least the number of their expected matriculating class by March 30. I'm not sure that offers much insight into how the Maine Track works. Tufts needs to have accepted ~200 students by now to comply with AAMC, but Maine Track obviously has more leeway being a sub-program within the medical school. Tufts' yield last year of accepted students who matriculated was 34% (
http://md.tufts.edu/About-Us/Class-Profile): 590 were accepted and 201 matriculated. So, to me, just being required to accept merely the number of your target class size by March 30 doesn't guarantee that they've even come close to sending out all ~600 acceptances yet.
Bottom line: I have no idea nor does anyone else.
