Thoms,
Quick answer, it's the math.
Can't work it out right now, yet shall tackle it tonight.
Mark.

The first example in 2/4 produces the short stem of the third 32nd note
pointing to the right.
In 2/8 it is correct.
Why?
Btw, I solves using \set stemRightBeamCount = #2 \set stemLeftBeamCount =
#3, but this should not be necessary.
Thanks
