I'm not sure we want to drop "completed" from this and all the following
descriptions.
There is a meaningful distinction between completed and dispatched
instructions, I think it's useful to be explicit about which the event
is counting.
I agree dropping "run" is a good idea, most people won't understand that
"run" means "non-idle", and I think don't expect idle instructions to be
counted anyway.

And here the meaning is different if you drop "completed".

All fair comments. I am looking for consistency, but correctness trumps.
Regarding consistency, though, there are lots of occurences like:
| "BriefDescription": "Average cycles per instruction when dispatch was stalled for any reason",
| "MetricExpr": "PM_DISP_STALL_CYC / PM_RUN_INST_CMPL",
Can we pick one phrase for all metrics where PM_RUN_INST_CMPL is used,
perhaps? "completed instructions" ?

Hi Paul,
Yes, OpenCapp is same as OpenCAPI. But as these descriptions
are provided by hardware team and same is followed in the PMU workbook.
We need to use OpenCapp.

Here using store unit is more appropriate as we are counting
instructions executed in the store unit of LSU.
