Not really, the idea is just to figure out in some systematic way who the dominant players were, and how they faired relative to one another. I'd take prime Federer-Nadal-Djokovic-Roddick over old Agassi-Hewitt-young Federer-Ferrero, for example. But not over Lendl-Wilander-Edberg-Becker. The depth and intensity of the 85-89 episode was quite something.
Well, maybe I don't know what you are trying to say, but I thought you were saying there is a connection between those numbers you listed and how strong the era is.
Here is an attempt to add some interpretation.
What could make a great era? Three things come to my mind:
-- An outstanding champion
-- A great rivalry
-- Great depth of competition.
Now say a dominant champion
is one who made at least 40 points over a 5-year period -- reduce this a little to, say, 35 before the mid-80s, when many players skipped the Aussie Open. Episodes that qualify are 05-08 (Federer), 85-89 (Lendl), 80-84 (McEnroe), and 75-79 (Borg). 95-99 (Sampras) is close.
Say a great rivalry
is an episode where at least two players scored 30 points or more. Episodes that qualify are 05-08 (Federer, Nadal), 90-94 (three-way rivalry of Edberg, Courier, Sampras), 85-89 (Lendl, Wilander), 80-84 (McEnroe, Connors), 75-79 (three-way rivalry of Borg, Connors, Vilas). 95-99 (Sampras, Agassi) is close.
Finally, say great depth
existed when at least four players scored more than 20 points. Periods that qualify are 90-94 (5 players: Edberg, Courier, Sampras, Becker, Agassi), 85-89 (Lendl, Wilander, Edberg, Becker), 80-84 (McEnroe, Connors, Lendl, Borg), and 70-74 (Rosewall, Newcombe, Kodes, Smith). 05-09 could still make it but it's unlikely. 75-79 could be added in as again scores are lower because of the poorly attended Aussie Open.
-- two episodes score as "great" on all three scores: 80-84 and 85-89. These years had it all.
- three episodes score as "great" on two scores: 05-08, 90-94, 75-79.
- one episode scores as "great" on one score: 70-74
- and two episodes score as "great" on no score whatsoever: 00-04 and 95-99. 95-99 is closer to "greatness" on most scores than 00-04, however.
If so, tennis is in a new exciting age after a period of relative draught -- and this pretty much how I see it.
