Each of them shows a completely different number. Especially "Index Explorer" vs. "Total Pages Indexed" I see on one site numbers like 227k vs. 474k. Other sites show similar differences. Quite difficult to understand.
Also with the metrics "Appeared in Search" there are huge fluctuations with long tail traffic, I was spending days to figure out what might be causing these fluctuations but it's impossible with the small data sample.
Hope they still work on making the data more accurate, I love all the reports.
