Well when you consider how accurate ioi usually is with his numbers when compared to MC/NPD/GFK numbers,it really shouldnt matter how many retailers ioi tracks as long as hes accurate.
In regards to making adjustments to other tracking firms,its only done when there is large discrepencys between VgCharts and the other trackers.I think ioi is right to do this as it only adds to the validity of the numbers on the site.
