28th August 1998 Minor changes to query page.
Prepared site for hibernation.
19th January 1998 Added option to invert the rating, since users may like to assume combinations drawn most frequently are less likely to appear in the future.
June 1997 Rating values are now exponential. Better combinations have a much higher rating value, which allows the search algorithm to prune off worse combinations more quickly.
All processes are now performed in the background.
April/May 1997 Program re-written in JavaScript - this allows visitors to the web site to preform their own analysis.
October 1996 Invented numerical method of assigning a rating to a pair of balls based on their previous meetings.
Devised scheme to rate lottery lines by combining pair-ratings.
Added search facility to find the best combinations.
Web-site updated with top 20 combinations for each machine and set of balls.
September 1996 Program re-written in Ada - analysis can be performed more quickly through this compiled language.
Added feature to generate results in HTML.
Created initial lottery site showing a table of most commonly drawn pairs.
March 1996 Due to the growing size of my statistics, I created a program written in BASIC for my home microcomputer.
The program stored all lottery data and output a tally of ball numbers for a given machine or set of balls.
December 1995 At the request of friends and relatives I began recording the lottery results.
Marking the results in a log book, I kept a tally of balls drawn by each machine and with each set of balls.
