I create this thread because I saw several credible sites backuping my theory and I wanted the answers. I respect ioi and I appreciate his work, so if he said „GFK figures are, and always have been, for 100% of the market based on a sample of 80% - just like every other tracking service.“ I believe him.
From the random person on the internet (not credible): „GfK covers 80% of the market in Germany, but in contrast to Media Create, Famitsu, NPD etc. the rest of the market isn't extrapolated. So these are the sales for the 80% tracked part of the market and the rest isn't there at all.“
People are confused, that's all, ...also, if someone say something, it's either his/her opinion or the fact, but fact must be based on credible source.
