thechartist has asked for the wisdom of the Perl Monks concerning the following question:

I'm interested in improving the reliability of CPAN modules on systems that do not get all that much attention, and MSWin32 seems to be one of them.

I have been studying the various CPAN testing documents, as well as checking out the CPAN testers log file, that gives the 1000 most recent reports.

This is off-the-cuff and not rigorous, but a quick check for "Linux" gives me around 600 of test results, "BSD" around 360, and "MSWin32" around 40. This suggests to me (making certain assumptions that the testing population represents the broad user population) -- that only about 4% of Perl users are on Windows.

Do those estimates seem at all accurate? Thanks for the guidance.
