Normally I would say that what you’re doing is at the very best sub-optimal and at worst harmful. However I know you are well adapted to this sort of overload then then rest type of schedule and from you own accounts it does seem to be working for you.
The most unconventional and troubling to my coach’s mind is the ME-Max-ME days all packed together. That is a very big local muscular loading that, if done correctly must leave your legs feeling totally worked. I would doubt the efficacy of the second ME workout is very high as there is no way you can recover from the previous 2 days.
But as they say> “If it ain’t broken, don’t fix it”. Given your time constraints This may be the best plan for you as unconventional as it is.
Good luck and keep us posted.
