These numbers aren't very usefull. Not trying to kill your arguments (still haven't read through your thread but I am going to after I write this).
Anyways, launches have high points in sales and so will the holidays, so all of the consoles are clearly going to be coming down right now. Then we have a situation where because the PS3 is closer to its launch/X-mas and also its EU launch (which was sizeable) its average is going to be deceptably high. Same with the Wii to a lesser extent (only reason its a lesser extent is it didn't have a EU launch in spring). The 360 is going to be deceptively low relative to the others because of same thing, only in this case its much farther from its launch.
A good way to use your method of averaging is to instead use weeks over identical periods (to preserve market condition factors) and eliminate outliers. You can determine what you would classify as an outlier but I would suggest setting it in advance rather than deciding when you know which consoles its for etc..., something like 3 standard deviations would do just fine in this situation.
Or you could simply use the Mode of the consoles over those periods.
If your interested I have some basic stats for each console as of current numbers... I will post them and if you want to you can use them. No worries if you don't, I get them from my spreadsheet automatically so its mostly copy/paste.
| Wii | 360 | PS3 | |
| Mean | 274,045 | 116,833 | 103,161 |
| Median | 249,472 | 88,255 | 84,102 |
| Standard Deviation | 107,886 | 88,208 | 81,920 |
| Q1 | 216,757 | 76,029.5 | 64,261 |
| Q3 | 278,310 | 111033.5 | 105,090 |
| IQR | 61,553 | 35,004 | 40,829 |
Those are based on weakly WW sales since launch of each console.
