I'm not sure what that means.

After doing a bit of research, I think it might be a bit more clear as:
"Average cycles per instruction when the NTF instruction finishes at dispatch"

Is "next to finish" some defined and/or sensible term in this context?
Or do you mean NTC here?  Or what :-)

Yeah I am also more familiar with NTC.

But those descriptions originally come from a spreadsheet we're given,
and they do include NTF as an acronym.

eg. search for NTF in here:

  https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/tree/tools/perf/pmu-events/arch/powerpc/power9/metrics.json

From the context it does presumably mean "next to finish".
