Playoffs are always a crapshoot. That's why we don't celebrate our World Series title from 2011.
If you look at the 1976-83 era, the Pythagorean W/L record rankings match the chronology, 1976 the best of the bunch, 1983 the worst.
1976 (swept in NLCS) .644 (better than the Reds that year, by the way)
1977 (lost 3-1 in NLCS) .607 (actually worse than LA)
1978 (lost 3-1 in NLCS) .586 (again, worse than LA)
1980 (Champs!) .559 (not as good as the KC Royals)
1983 (NL Champs) .542 (yet again, worse than LA, and worse than Baltimore)
Then look at the other championship era, not a match for the chronology this time:
2011 (lost in 1st round) .633 (much better than StL)
2010 (lost in NLCS) .585 (a smidge higher than SF)
2008 (Champs!) .573 (higher than all the teams they beat, not as good as Boston that year though)
2009 (NL Champs) .566 (worse than LA and NYY)
2007 (lost in 1st round) .538 (worse than COL)
And the current era, this one goes from best to least best in reverse chronological order.
2024 (lost in 1st round) .571 (better than the NYM)
2023 (lost in NLCS) .549 (far better than AZ)
2022 (NL Champs) .540 (worse than all the teams they played in postseason except SD)
(just for fun, the 1993 pythagW/L for that NL Championship team would fit in between 1978 and 1980 on the first list, between 2010 and 2008 on the Utley era list, and between 2024 and 2023 on the current list).
