Here are some stats for 1998
 
Here are the player results files for all of 1998.
Warning: if you download the files and open them in a word processor, you will have to choose different
than standard settings (like minimal page margins, landscape orientation, and an 8 point fixed-width font)
because there are many characters per line (about 130 or so).

Again, I'd like to thank Jelle Kok for helping me build my database.  I wouldn't have been able to
create any of these without him.
