See my comment here for Workspace.   https://experienceleaguecommunities.adobe.com/t5/adobe-analytics-questions/data-mismatch-between-workspace-and-report-builder/m-p/543281/highlight/true#M38907   Basically workspace has some attribution settings that can differ from Adobe regular reports. Linear i...

ok one area that workspace can cause such a variance is in its attribution assignment of data   In settings on workspace. look for Attribution IQ to modify the allocation to "Last Touch" (or Linear which I think may work in your case). Play around and see if you then can get the data to match betwee...

Then it could be how each has  2 sources. which kpi is difference in?   PV , UV or visits?

Did this data pull occur where data in same day could have been changed from the initial times each report was pulled? IE if one pulls data for present day 9am Workspace then an hour later you pull it from the other data Warehouse?    

What if you set a direct rule rule on the specific link click and just use it to set an set variable (event number in your case). the the exit link would hopefully just add the extra event in its beacon. The only challenge is ensure set variable fires before exit link i rule fires.

There is no work around in sense of increasing it in same variable.   I copy to a new evar which then has a limit of 512 if memory serves me.   GLTU

I am not aware of any limitation by sheer numbers processed.   I suspect the sheer volume you encounter is just having instances/variations that though they seem to should fall into one classification are somehow being processed as unspecified.   Could there be some logic that when so many are sent ...

First question how are you classifying things.   Using classification rule builder or Uploading files to be classified?

There is also: Return Frequency you may find useful   regards
