There is at least one method of measuring it without resorting to

perfectly accurate? Of course not. But there are a number of

versions of Windows have a total usage share ranging from 80% to 90%.
True enough.
How many web crawlers have you built? Are there any web programmers
out there who need a web bot to hit multiple sites zillions of times a
month from different places on earth to 'up' the number of hits for
economic reasons? I've seen my share of this.
How mamy times have you altered the identity of your web browser so
that the web site would 'work'? You know, stupid messages from the
server that say, "We only support IE 6+, upgrade your browser...", so
you tell it you're using IE 6 and, well no problem.
Web site data is bogus. It assumes even distributions... it assumes
even usage of the site from all surfers, it assumes no web crawlers and
no bots, it assumes no browser identity tampering, and it assumes that
there aren't those who for economic reasons are not inflating the
numbers deliberately (no, really??) from world-owned bot farms.
There is no reliable way to measure free software usage. But, there
sure is a lot of posturing going on in the market place ... wonder why?
kind regards,
