RE: Margin of Error

I believe that my numbers should be accurate within 1-2%.

Basically, when Iomega gives numbers like "Zip unit sales increased 34% this quarter, Zip OEM unit sales increased 56% this quarter, and the OEM percent was 52%", you can calculate quite a few other values. Since the Iomega percents are only accurate within 1%, the calculated values are only accurate within about 2%.

There are very few actual "estimates" in my numbers. For instance, the baseline of my numbers is in Q4 97 when they said that they shipped "about one million drives per quarter". The calculations go backwards and forwards from there with the publicly released percents and increases. I did make some guesses on some of the 95 numbers, but I'm not sure I even included them in my stats page. They're on a separate spreadsheet, I believe.

The cumulative numbers essentially match up with the milestone announcements, which lends some credibility to my numbers.

It might be more accurate to say that my numbers are somewhat imprecise, although a precision of 98-99% is good enough for me.
