I’ve been quiet a while, because I’ve been a little busy. A version of the simple ranking system, favored by Doug Drinen, is now coded as a CPAN module. CPAN, the Comprehensive Perl Archive Network, is a user contributed library, and thought to be Perl’s biggest strength.
The object that the SRS module creates can be used as the parent for other analysis, which is one reason for contributing it. A module that inherits function from the above also gets its game parsing functions for free. That’s one reason I went that route. Since I’m eventually wanting to think seriously about the “homemade Sagarin” technique in a reproducible way, this is a place to start.
