3 titles purchased by every wii owner is taking the total number of wii games sold and dividing by console ownership.
While the second figure is derived by dividing total number of wii games sold by the total months a console is owned instead of total consoles sold.
For example, say there are 4 wii consoles, and they sell 12 games over the year.
That would be roughly 3 titles purchased by every wii owner.
Now say, of those consoles, 1 had been owned for 12 months and the other 3 had been owned for 4 months each. So out of a total of 24 combined months of ownership 12 games have been sold. So they have sold 2 games per month.
This second method, while trickier to calculate is less biased then the first model, which is biased towards sysems that arn't selling well. Take the PS3 for example, which until recently hasn't been selling well after a huge burst at launch. It's attach rate would be much higher, as the average length the system has been owned is higher, therefore people have played through the games and bought new ones, while your raidly new expanded Wii owners who just bought the system last month have yet to get tired with Wii sports.
Of course it's not a perfect science since people tend to buy 2 or 3 games at launch. But it's still a slightly better indicator.
