For whatever reason VGC hasn't been using exact NPD figures, instead they've been splitting it down the middle between their set of data and NPD.

Yeah which i find bizzare you either stick with your guns or go with NPD numbers, going down the middle is just random as its not a number anyone tracked.

No it isn't.  If you have two experts, one says 9 and one says 10, then saying about 9.5 is a reasonable thing to do.

Now, in this case I think VGC is being a little arrogant since NPD has a larger sample of data so they should weigh NPD's estimate more.

But this is one "Expert" changing there answer not somone taking an average, so they had no faith in there own answer to begin with, 

As you wish, but VGC is not an authority - they just aggregate and model based on various bits of data.  NPD is just another data point, but since NPD takes a long time to aggregate their data, then the initial estimate is 100% other sources, while after NPD they have 50% NPD 50% other sources.

It's only after manufacturers make official statements that they might fully adjust.

Again though I think that with NPD covering around 65% of the market they should be given a large weight.  At the same time VGC can't just plagiarize NPD.
