# Lyrics, tuplets and duplicate to staff above/below

I have run across a problem. If I have a phrase with a triplet in it, and copy the lyrics using “duplicate to staff below” the lyrics shift out of their correct position.
It works fine if I just copy and paste the lyrics; I wonder why it does not do the same with the “duplicate to staff”. Example attached.

Did you make sure that the triplet was selected before copying?

If you select the triplet (number and/or bracket) along with the lyrics, their rhythmic value is copied correctly.
I also would like Dorico to do this automatically, it’s a bit annoying. Especially since you have to re-select the tuplet again if you are duplicating the lyrics to several staves below. Currently, the lyrics remain selected in the duplicate, but the tuplet doesn’t.

I have a question to the developers, on a more fundamental level: why do tuplets behave like independent objects (like they also did in Sibelius, to my annoyance TBH)? Why aren’t tuplets merely a notational device for representation of non-binary subdivisions? IMHO, say, a group of 3 quavers in a triplet does not actually consist of quavers (eighths), but of twelfth notes, for which the tuplet notation is just a way of writing them in our established binary system.
If I select and copy a passage only consisting of binary rhythms (say, a quarter/crotchet followed by two eighths/quavers), I can paste that rhythm anywhere, and the durations will be preserved, even if the notation gets considerably different from the original. Dorico is good in doing the math.
But if I select and copy a 1/12 note, I actually would like to be able to paste that same twelfth note elsewhere, and let Dorico again do the math of determining the best notation, which in some cases will involve adding a triplet around it, or in some other cases just fitting my twelfth note inside an existing triplet. I mean: the tuplet should not be a thing in itself, ‘containing’ notes, but the result of notating a non-binary subdivision.
