It seems as though Meditation never scales with your level, while of course, your energy degeneration does.
At higher levels it'll be almost useless to meditate since you'll lose the majority of that energy on the next degeneration tick.
I currently use Focus Energy with MA2 and get a "max relax" of 24 energy. This hasn't changed throughout my many level gains.
I could get MA3 but that'll make it useful for only a short while before the same problem happens again. Same with Bubble Tea.
