I'm pretty sure that OSes usually send TRIM right away and let the drive figure out optimization. Wikipedia says "some distributions" of Linux turn it off but my various ubuntu-ish systems have `discard` or `discard=async` in the output of `mount`.
"last retrim" on Windows is an extra feature, because TRIMs can get dropped when a drive is busy enough. It goes through all the free space and TRIMs it again once a month.
Also even if you did only TRIM once a month, I think most of your free space would still be zero.
