Description:

This is my first attempt at hacking together a simple application using
Delphi.  I used to code in Clipper (DOS world) so this was quite
the culture change moving to Windows.  I originally wrote this
application (called US Rating Calculator then) a year ago in
Powerbuilder but it wasn't a true compiler and I heard good things
about Delphi so I re-wrote it.  Chess Rating Calculator (CRC) doesn't
have any database access because I don't keep any of the values.  It is
simply a calculator (based on the USCF rating system) to see how your rating
changes depending on the strength of your opponents and whether or not
you are playing provisionally (less than 20 games).  It doesn't handle
bonus points because in general you won't know if your opponent's play
warrants you receiving any or not.  I didn't write it for general
distribution but several people on the Internet requested something
similar so here it is.  It is free to use, the only thing I ask is you
send me an Email message letting me know that my upload wasn't wasted!  My
Email address is listed at the bottom of this file.  It isn't finished
yet, I will pretty it up someday and add a real help file and maybe
database access to keep the last rating or previous scores or something.
Any suggestions you may have would be appreciated.

System Requirements:

Chess Rating Calc is completely self-contained and is compatible with
Windows 3.1.  It hasn't been tested on versions of Windows prior to 3.1,
OS/2-Win or Windows 95.  It really doesn't do anything fancy so it
should work in all the aforementioned environments.

Installation:

Unzip the files into any directory of your choosing and either use file
manager to run the program or add the application to a group  (pick an
existing group of your own choosing or add it to a new group) with the
File/Insert/Item menu options.

Instructions:

Enter your previous rating in the box provided and click on the radio
button whether you are provisional or not (default is that you are an
established player).  If you are a provisional player it will ask how
many total games you have played.  Fill in the game boxes with your
opponents rating(s) and your result (win/lose/draw).  You can enter up
to 10 games and then click <CALC>.  That is all there is to it!  The
<RESET> button clears the scores and takes you back to the top to start
over.  Ignore the drop down list that gives the ¬k option.  This isn't
implemented yet and I may also use that for adding other rating
systems besides just the USCF, that's one of the reasons I changed the
name from US Rating Calc to Chess Rating Calc.

Hope this is of some use to you.  Remember to send me an Email msg. with
your comments or if you are experiencing any problems.

CRC.EXE was developed and compiled using Delphi 1.0 (tm) from Borland
International.

Version Information:

12/11/96 1.1 (beta)

Changed the K factor formula to reflect the latest values from the USCF
November 16-17 Policy Board meeting.  The new values are as follows:

Pre-event rating/K
 400/72
 600/64
 800/57
1000/49
1200/42
1400/35
1600/28
1800/22
2000/18
2200/16

I'm assuming that less than 400 is also 72 or they made 400 the absolute
lowest possible rating, in which case I'll have to make a change to
refect that.

08/28/96 1.0 (beta)

First release, or at least the first Delphi release anyways....
