1970 Computer Rankings

I did a top 100 Computer Ranking List based on the updated 1970 results page. I was pleased to see that it didn't vary much from the "official lists" of the experts of the day. I'm always interested in those outside the top ten that don't get much credit for their achievements.

Re: 1970 Computer Rankings

Very cool PF.

How did you calculate it?

Also interesting to see Ann Jones top ten despite opting out of defending Wimbledon. She went on to have a good 1971 as well.

Re: 1970 Computer Rankings

Just gave point values to events based on quality of field and reputation of the event. 100 for Wimbledon winner, 70 for French and USO winner, on down. Some events were so minor they might receive as little as .5 for the winner and some local events no points at all. r/u got 60-70% of winner and so on. Fields for some events vary from year to year, so I leaned heavily on how many top players were in the field. I took the top 12 results for each player. My experience with that era is that some players played 25+ events and others played less than 10. The experts seemed not to punish those who played little nor did they reward those who played a lot. 12 seemed to be a fair number because the experts often ranked players in their top tens who played only a handful of tournaments.

Also I ran the year from the conclusion of the Dewar circuit in 1969 through the Dewar circuit in 1970.

Ann Jones played exceptionally well, but simply didn't play the Slams. You wonder what she might have done at the French or Wimbledon. From what I've heard, though the Wimbledon final was a classic in terms of being close, it wasn't a classic in terms of quality of play. Both players were somewhat hobbled.

Goolagong won all over the world, but most of her wins were in 2nd level fields over players like Joyce Williams. Still, not bad for an 18/19 year old.

Richey had knee trouble and only made the top ten after a late summer/early fall run. Glamorous Helga Schultze Hoesl was interesting. She played almost solely near home and on clay, but had great results even winning a strong German Open. She played so little she only reached #29.

Vlasta Vopickova (Jan Kodes' sister) may have had her best year on the international level at #21. She was a French QFist and reached the R16 at Wimbledon.

12 is a reasonable number. In my private rankings I use the best 10.
