Unlike NPD or GFK ioi is a single person who estimates. You are also same; a lone wolf using excel and others to estimate data. A few correct estimations don't make you equal of NPD groups reputation.

Do you have me confused with someone else?

I only post reputable data from organisations such as The NPD Group or GfK.  I don't post my own estimations with any authority. 

I haven't confused you with others. I am meaning you. Plus you "indirectly" enjoy the fame of the estimator and dare to question others; while having no guts to make a decent site that will post sales updates.
