Nah recount is trash. It has highly variable results. I'm not sure or if it's consistently in accurate or it just so happens to be grossly inaccurate on certain people's characters on default settings.
I used to see myself doing 30-40% more dps on it and others doing lower amounts. I then saw on Warcraft logs that I was way worse than I thought.
If op uses details he will see himself doing way less damage. I think the issue with recount is something to do with it not recording downtime for yourself accurately, nor the actual uptime of others.
You could be doing 30k dps whenever the addon is tracking but have like twenty percent downtime and be doing shit numbers.
Stopped using it in uldir because of this and details has been nearly one hundred percent in line with Warcraft logs.
