He was making fun of people who say that by using well-placed sarcasm. However, apparently even his little smilie face couldn't tip everyone off...
I don't see a wink smilie anywhere :p
Note: Some games in my collection are no longer owned, but have owned.
The smiley is there, but it shouldn't be necessary anyway... Oh well.

How close is VGC to NPD usually, and do they make adjustments?

add me, the more the merrier.

Usually within 15%. There were some adjustments in the past, but nowadays vgchartz doesn't adjust to NPD. As far as I know, shipment numbers from financial reports are used for adjustments instead (taking into account that they're shipped to retailers, not sold to consumers of course).

Not bad really, I am sure that VGC would like to be able to get it within the .05 alpha, but not bad.

It's really impossible for any tracking service without 80% retail sources to ever have less than 10% margin of error. Even NPD isn't anywhere near this, and their numbers have in the past been far off of reported shipping numbers. Media Create and Famitsu both hold about 60% retail data for Japan and yet disagree greatly on various things. Being wtihin 15% is pretty good. Past that VGC adjusts to official shipping reports and releases comparisons to NPD numbers.
Any update to the time frame?

Media Create is holding over 90% of retail data, ChartTrack to, NPD ~ 65%

You are misinformed. Media Create and Famitsu both operate on ~ 60% retail data. NPD is somewhere between 60% and 65%.
