I think it's going to be tough to get an actual answer on this unless you find some seriously hardcore math people. I could be wrong, but I would think that most people's attention is taken up more with the actual dyna run than keeping track of,
Did JOB/000 person trigger?
Was it clean and not chatlog error? (Giving incorrect name.)
How many weaponskills/JAs did JOB/000 perform on
each mob?
Was every proc attempt made during the correct time?
What was the total number of mobs?
It's probably going to be a thread of,
"We got 2 white !!s on our last run."
Which isn't very helpful.
I'd say, if you're happy with your records, then the number is whatever you came up with - at least for you.
