I try to use actual data with some kind of markup to account for unknown data, when possible. January was particularly nice for Wii, since Nintendo told us it was at 370K for the first three weeks in Europe, so I assumed constant sales in Week 4 and got ~480K for Europe. I then added 70K to try to compensate for other regions not named U.S., Japan, or Canada (e.g. Australia averaged ~35K / month in the first half of 2008 and that average increased in the second half of the year, so that should make up a good portion of the markup.)
Usually, there isn't as much recent data to go with, though. As sort of a placeholder number, I'm currently using 75% of U.S.+Canada as "everything else" for 360 and 95% of U.S.+Canada as "everything else" for PS3 unless more accurate data is available. This is based on Nintendo's report of European weekly hardware sales through CW41 for 2008 (with a ~10-15% increase for all non-European, U.S., Japanese, or Canadian territories) and comparing it to the U.S.+Canada monthlies in the same timespan.
Not a single formula, in particular, but just trying to fit with the available data, whenever possible.

HK-47 said:No because he admits they are estimates, but explains how he calculates them and uses solid numbers whenever possible.
Thanks!
