Problemist Tables

The tables shown below are obtained using Rel, a free download provided as Open Source software by Dave Voorhis.  Rel is an implementation of Tutorial D, a relational database language invented by myself and Chris Date.  The first table shows problemists scores to date for the present year.  The second  shows the final positions last year.  The third shows total scores and grades for all problemists who have been active since January 2011.

Until January 2011 I had been using a suite of computer programs developed by myself in Mallard Basic, originally on an Amstrad PCW running CP/M in the early 1980s.  In that system I was unable to retain detailed records for previous years.  I had wanted to switch to Rel almost as soon as the first version of that product became available in 2004.  I was compelled into action in 2010 when I discovered that Mallard Basic, developed originally for CP/M and later for MS/DOS by a company, Locomotive Software, that no longer exists, is not supported on Windows from Windows 7 onwards.  Thanks to Rel, I am now able to retain detailed records indefinitely.

Problemists active since January 2011

The high total scores for some of these people is explained by the fact that they were participating in solving competitions in the days when I was publishing them in British bridge magazines.  The entries are shown in descending sequence of scores obtained since January 2011.  The last two columns reflect only MPs and SPs arising from Difficult Ratings of the monthly competition problems; they don't include points added for other reasons, such as solving Competition Problem 1.
