How the "Generations" are actually faring at the US Open

G.O.A.T.
There are five generations playing tennis at this tournament. You can quibble with the methodology of how I broke them out, hardlined on specific dates, but it's all pretty minor stuff. Yes, Thiem is listed as Lost Gen here. Yes, he's probably honorarily considered Next Gen.

Fed Generation (1980-1984):
There are only 7 players in this group. I actually added Ivo Karlovic, the one exception I did in breaking out the generations, because he was born in 1979, and would have been in a generation of his own. Only one of the 7 got a win, Gilles Simon. The generation finishes 1-7.

Djokodal Generation (1985-1989):
There are 25 players in this group. Headlining is, of course, Novak Djokovic, the only one that has made it to the 4th round. All 3 former Grand Slam champs hail from this generation. Mikhail Kukushkin, Roberto Bautista Agut, Adrian Mannarino, and Marin Cilic all got 2 wins. Novak Djokovic, in the ball swat seen around the world, is unceremoniously dumped in the 4th round by DQ. The generation finishes 15-25.

Lost Generation (1990-1994):
There are 49 players in this group, the largest in the competition. Pablo Carreno Busta and Dominic Thiem have made it to the QFs. Vasek Pospisil, David Goffin, and Jordan Thompson have made it to the 4th round. Jan-Lennard Struff, Ricardas Berankis, Marton Fucsovics, Filip Krajinovic, and Salvatore Caruso all got 2 wins. The generation holds a 41-47 record.

Next Generation (1995-1999):
There are 42 players in this group. Alexander Zverev, Borna Coric, and Denis Shapovalov, Alex De Minaur, Andrey Rublev, and Daniil Medvedev have made it to the QFs. Matteo Berrettini, Frances Tiafoe, and Alejandro Davidovich Fokina have made it to the 4th round. Cameron Norrie, Karen Khachanov, Taylor Fritz, Stefanos Tsitsipas, JJ Wolf, Casper Ruud, and Corentin Moutet all got 2 wins. The generations holds a 58-36 record.

Baby (TBD?) Generation (2000-2004):
There are 5 players in this group. Felix Auger-Aliassime headlines and has made it to the 4th round. Only other winner was Brandon Nakashima. The generation holds a 4-5 record.

Djokodal25152537.5%
Lost49414746.6%
Next42583661.7%
Baby54544.4%

There have been 120 matches and in 74 of them the younger player won (62.1%). There have been 38 ranking point upsets (ie lower ranked player beat higher ranked player) for an upset rate of 31.9%. The biggest upsets so far were Kuznetsov-Querrey and Sock-Cuevas, however those were pretty unusual circumstances with 2 players attempting to resume careers. Michael Mmoh (#186) winning against Joao Sousa (#68) and JJ Wolf (#138) winning against Guido Pella (#36) were probably the biggest actual upsets. In 31 of the 38 upsets, the younger player won (81.6%).

I've broken down the inter-generational H2H through the first three rounds:

Thanks. This needs context. Is 61% winning percentage for the younger player typical?

Tbh, I'm not sure. It seemed a lot higher back in the day, then we had the recent trend of older players extending careers and gatekeeping against the younger players. I am indeed just trying to put everything into context, though.
