As you observed, MLife tier qualifying year begins October 1st. I re-upped for Platinum for 2016 (10-1-15 thru 9-30-16) by early January of 2015 (3+ months). There are probably others that are "Noir forever" (if there even is such a thing), while it might take others 11+ months to attain Gold or whatever.
As others have opined, simply "playing for status" (in ANY program) is statistically and financially a bad idea and a poor proposition. In my case, "status" is just something that happens by virtue of the frequency and level at which I play. That is to say status level (any level) is something that just "happens", not something I'm directly focused on attaining in and of itself.
YMMV
I did get to Platinum level in Mlife before I quit.
I'm close to requalifying for 7* in CET--but getting beyond 150,000 TC doesn't get me enough extras; at 250,000 TC a few more nice things happen.

[Borgata in AC
had a link with Mlife, which was severed...there are rumors it may be restored--that would be even more of an impetus to switch to Mlife.]
[CET
may have to be dismantled--so having another system to play in could be useful to me.]
