Despite the increased reports of confusion (and the fact it intuitively makes sense) I just can't find the numbers to back it up. Comparing days 0 to -30 against -60 to -90 the ratio of hits for downloading CCCP vs. CCCPi has increased.
Correcting for changes in absolute visitor counts, the number of Insurgent downloads has fallen ~15% and the number of CCCP downloads has increased ~4%. If anything, people are less confused now.
For the record, downloads are split about 95:5, up from 90:10.
I still think the number of insurgent downloads is higher than it should be though, so i'll spend some time making the insurgent link less obvious.
