INTRODUCTION
The current ASA Equivalent Performance Tables were computer generated by SPORTSYSTEMS using the same rules as the EQVTIME computer program. This program and the printed tables are the official basis for all time conversions used for Championship entries by the ASA and its constituent clubs, counties and regions.
These tables are a reworked and expanded version of the original EQUIVALENT PERFORMANCE TABLES developed by Rex Smith.
Four new tables have been added to cater for the 50 metres on each of the strokes. The range of times covered by the tables has been reviewed in line with current World Records, National Standard Times and the lowest grade of the Graded Swimming system.
The tables have been determined and printed using modern computing methods, however the rules for converting times has been retained. Where differences from the original tables occur they are due to the inherently greater accuracy of the modern digital computer and to the direct transfer from computer to printers artwork.
The program for EQUIVALENT PERFORMANCE TABLES has been available for download from both the British Swimming and SPORTSYSTEMS web sites since 2004.
With the widespread use of computer systems for tracking swimmer performances, producing ranking reports and aiding team selection and meet entry tasks the underlying rules and programming libraries are now being freely released for use across the sport.
This release is in two forms:
Both of these versions are available as a download from the SPORTSYSTEMS and the British swimming web sites.
