Winning Percentage 1869-2009

This script computes and displays winning percentage over a given time span.

This script operates on data from James Howell's web site. Thanks to James for creating and maintaining his excellent database.

Note: James' site contains only data for years when each team was considered 'major' (equivalent to today's I-A), and therefore will not necessarily yield true 'all-time' results.
