I'm not trying to derail this thread, and I don't want to cause a massive argument, but once and for all I want to use a real example with numbers to show how the data in VGCharts is produced, and anytime that someone tried to argue (Jonnyram, CoolTrick, A Link to the Past or whoever their successor may be) then someone can point them to this post.
Let's use Brain Training (Brain Age).
- Nintendo released a fancy press release about Brain Age that as of the 6th of August the game had sold 3m in Japan. They actually mean shipped most likely, and since other numbers (500k Europe, 600k NA) were quoted to nearest 100k, it's likely that the actual shipment figure was 2.95 - 3.05m as of the 6th August.
- As of the 6th August, total sales for the game stood at 2.65m according to Media Create and 2.61m according to Famitsu.
- The document referenced on the previous page shows that Famitsu's estimated shipped and sold numbers for Brain Training as of the 16th July were:
DS 東北大学未来科学技術共同研究センター2,561,530 2,506,497 97.9%
Showing a 97.9% sell through rate and 'stock' of around 55k, or between 1 and 2 weeks sales.
- Assuming a similar value for stock on the 6th August (totally reasonable looking at that document and seeing that all games seem to have around 1-2 weeks worth of sales difference between the shipped and sold figure) would give stock of around 60k (taking it a little on the high side).
- Now, only a fool would disagree that we have a number of discrepancies here. Using Nintendo's 2.95-3.05m shipped number and assuming the 60k stock we get from Famitsu, we get a sell through of 2.89-2.99m.
- Take even the lowest figure (as I'm sure you will all want to) and you have:
Nintendo shipped - 'stock': 2.89m
Media Create: 2.65m
Famitsu: 2.61m
- Nintendo's shipped number is ACTUAL. They will keep a record of each game that goes out of the door.
- Famitsu and Media Create's numbers are
estimates. Their
best guesses of how much the game has sold by covering a certain amount of retailers (around 50% each I think) and extrapolating their sampled sales up to estimate the sales across the whole country.
- Which one do you think is most accurate? Data that comes from 100% of all games, or data from 50% that is scaled up? Data that will probably miss online sales, non-gaming store sales etc and
guess to try and account for them?
- Divide 2.89 by 2.63 (the Famitsu and Media Create average) and you get 1.099, so 10% higher. The same figure that I have been using for the last year to scale Brain Training up by. Magic.
VGCharts said:
Brain Training 35,250 / 2,896,000
As far as I am concerned, the data is as accurate a representation as physically possible of how many copies of a game have actually been sold. I completely stand by the methods and the reasoning behind them.
And when it comes to the question of an explanation on the site as to how they are arrived at:
1) I am working on one
2) It is difficult to explain the above without using numerical examples and unfortunately since every game is a slightly different case it is virtually impossible for me to produce a 'cover-all' explanation.
3) I don't, and never have had, any intention of misleading anyone or so forth. 99% of the data on the site comes from methods just like shown above, using a variety of sources to produce what I think is the most accurate data overall.
4) I'm not trying to 'compete' with NPD / Famitsu etc, my data is BASED ON theirs!! All I am doing is using multiple sources to come to the most accurate conclusions possible, since they all disagree slightly with one another.
5) If you don't understand this then please don't argue with me as it is obviously over your head and anyone saying my data is "estimated", "made up", "bullshit", "inaccurate" or otherwise has no idea of what they are talking about.
Thank you and goodnight! (it's 2am here and I need my beauty sleep)
