There have been a lot of talk about if the depth of the field is greater now than what it was some 20-30 years ago. But is that really the case?
I thought one way
of measuring it would be to count the results going according to ranking at every slam played during the open era.
During a slam 127 matches are played (assuming noone retires). If most of the matches goes according to ranking, one could assume the depth isn´t very good and vice versa.
Now I´m too lazy to look for stats myself, sorry! But if anyone is interested looking for stats, please write them here and the percentage of matches going according to rankings in slams during the open era.
