Anecdotally, a friend checked in to MATSG-21 back when a month or two of downtime in the pool was standard. He tore his ACL doing MCMAP at the end TBS, so he became the MOC daddy (student managing the pool) for a very long time until he finally got cleared medically. He then had another month or two of downtime, so obviously they made him do MCMAP. It should also be obvious that he then tore his ACL again.
Our peer group is in the fleet, and his flight suit Friday was last month. MCMAP with caution, or more preferably, not at all.
