Stickball the worldwide prediction league averages are way high for 360 and Wii..Did people put in ridiculous numbers or is there an error? No way both will be in the 30,000,000 range by year end.

I think I was going through the predictions once and saw at least one person who had an insanely high number (in the billions) for the Wii. There are also peope who seem to have reasonable numbers, except they input them in millions and not in units (ie writing 13 instead of 13,000,000).

EDIT - here is an example of stupid numbers:

EDIT2 - a nice way to handle this would be to first calculate the average for all the entries, and then calculate it again but ignoring numbers with a standard deviation which is too high.
