ok. I do not see why we need three pages of beef here.
VGC does not charge for the numbers, they generally do a good job. The database is very useful. The numbers are about 95% accurate after 4-5 weeks. So if you are really that concerned look at the data 1 month late. Just discipline yourself. Always read the week 5 before the current.
As for me I usually have a hunch when VGC is off, and I ussually can tell myself a certain number is wrong. I thought VGC was too low for March SSBB and too high for April GTA4(and PS3/360 hw) and I was right...
If I was paying for these number I would be concerned... BUT THEY ARE FREE!!!
