This took me a few hours of practice and training (and frustration), but I finally managed to beat a song on expert+. I was certainly exhausted at the end of it (I did take frequent breaks) but rather happy with only missing 14 blocks.
Please bear in mind I am still new to Beat Saber (less than 24 hours of playtime) so cannot clear expert+ songs quickly or easily, but I'm learning very quickly. Its an immensly fun VR experience :)
As always, thanks for watching ^^
