I'm using Google Analytics event tracking to count the number of unique users that did some action on my site. A flag on localStorage is used to determine who is new and who is returning. I am aware that incognito or clear cookies makes the user looks like a new one, that's ok.
The problem is that on the GA reports screen there are 10 different numbers for the same single event! Which one is correct? What do the other numbers mean?
Normal Precision setting:
Total Events 12958 % of Total: 25.16% (51494) Unique Events 12599 % of Total 26.36% (47790) Event Category Total Events 58805 (100%) Unique Events 57241 (100%)
Total Events 26045 % of Total: 31.64% (82313) Unique Events 57241 % of Total 33.28% (76158) Event Category Total Events 58805 (100%) Unique Events 57241 (100%) <-- same as before
