Re: How many titles did ATP Year-End NO.1 players win in that year?
Interesting info (IMO) I found looking at the '77 results on the ATP site -
There were 101 tournaments in '77 compared to 68 in '05, and 16 of the events in 1977 had draws of 16. (small size surprised me) Far more players today competing for fewer titles. I didn't notice an MS level in '77, just grand slam or grand prix, so I'm guessing (post if you have other info please) that players were only required to enter the slams(?), so there weren't any mandatory top 64 player draws like PLO, Miami, etc... ? The AO had a draw of 64 that year and was played on grass. The USO was on clay with a 128 draw, same # as French Open and Wimb.
From a quick count (which might be a little off?) in 1977:
29 hard (24 outdoor hard, 5 indoor hard), 24 indoor carpet, 36 clay (33 outdoor clay, 2 "other" clay (?), 1 indoor clay); 10 grass; 2 unlisted - Washington & WCT outdoor on __?
2005 for comparison:
29 hard, (20 Outdoor Hard; 9 indoor hard), 8 Indoor Carpet; 25 Outdoor Clay; 6 grass
