I'm still baffled. I'm pretty sure you can find no human musicians
that can play notes in a 7919/4451 tuplet accurately, especially if
there is someone or something sitting next to them playing a 7909/4447
tuplet. If there is no human performer, then why are you using
LilyPond, which is a program for printing scores? Are you trying to
print these scores?

Yeah, those poor composers. They write 7909/4407 tuplets, and then who
would think that things break. Maybe the poor composers should try to
use Sibelius or Dorico instead? Also, I've heard you can typeset
tuplets with Finale too.

Good luck.
