No it would not and Yes you are wrong. The reason is very simple and most people here do not seem to grasp how GfK works. GfK tracks 80% of all retailers and fortunately these 80% include _all_ the major retailers in Germany. These major retailers account for roughly 95% of all sales, so therefore there is no need for GfK to go after the remaining 20% retailers ("Joe's computer shop", "Jack's used car and computers"). Like it or not, The numbers on VGC now are much closer to reality than they were before.
