Not sure if this is a bug of a limitation in what  ever function(s) are being used to calculate activity but when solo or on a target dummy activity is out of whack. Like 2000+%. It is accurate inside a raid or party just not solo.

Is that even fixable?

For example:

Actually this happened in an LFR testing against other BM hunters

Activity time is Waaaaay off.

It seems for the most part it collects the correct activity at the end of a fight but during it often swings wildly even above 10,000%

Here is the fix for the whacky in-combat numbers.  In Skada.lua change: 

function Skada:GetSetTime(set)
        if set.time then
                return set.time
        else
                return (time() - set.starttime)
        end
end

 to

function Skada:GetSetTime(set)
        if set.time and set.time > 0 then
                return set.time
        else
                return (time() - set.starttime)
        end
end

There is a related problem for "trivial" segments which are current.

I think the fix is in Skada:EndSegment() the updating of self.current.endtime, self.current.time and the call of setPlayerActiveTimes need to be moved out of the trivial set test.
