Thank you!

You're right, the matuvu combo still isn't easy at all, but with some practice the success rate of the combo will actually become quite reasonable. Only getting the 3rd matuvu will still require some luck, but in my opinion succeeding in this combo is probably easier than succeeding in the old 3 matuvu combo and the last matuvu combo together.

I guess you're asking about the theoretical maximum in FC? (My personal score in FC didn't change yet, it's still 50200)
According to
Maz' solution, together with the latest version of the dwarf combo, the maximum in FC without glitches is 53560 points. With Lance' version of the matuvu combo in part 2 (include all 3 gems on the trampolines in the combo), the maximum is 53650 points.
With glitches you can make the following improvements:
In part 3, you can equip the vortex, perform a SJ and get all 5 piggybanks and the yellow gems in combo (+430 points). Furthermore you can get some more points in the fairy hole combo (by starting the combo with the vortex from the last room) (+110 points) and in the tribelle combo (thanks to a SJ, which allows you get the vortex without making the stone squish the crab) (+490 points).
With these improvements the maximum in FC with glitches is 54680 points. However there are still some ideas for the fairy room and the tribelle room in part 4, so this might change soon.
Also thanks for the answers regarding TOTL 2! I completely forgot that you'd have to exit the first room a second time. The fact that the ceiling is solid, even adds to the problem. But, actually, sometimes it's still possible to clip through such ceilings. For example in LOTLD2 I found two SJs which allow you to pass the actually solid ceilings in the balloon room and the grim keeper room, so I think there's still some hope.
