So if none of the trackers get every single store, does that mean that the number of sales is definitely more than what all the trackers report? Or do trackers do some kind of adjustment to account for stores they are missing?
That I'm not exactly sure about. I know that NPD directly receives sales data from 90-95% of retailers and estimates the remaining 5-10%.
However, I'm not exactly sure if the sales figures provided directly reflect the sales from ~3,000+ stores that agree to share their data with the trackers, or if they estimate the remaining market and factor that into their calculations.
The reason is because I've received conflicting reports on the exact methodology of their data.
I believe Famitsu sales are an aggregate of the 3,600 stores they receive data from. I'm not 100% sure about this, but it seems to indicate that from their f-ism website. Dengeki sales often end in "000" much more frequently than they should, so it seems most likely they combine real sales data with their estimates for the market. I'm not sure about Media Create.
