Reading up on this more, it seems to be based on stadium/venue capacity, which means any possible TFRs are at a limited number of areas for very specific series, for which there is data available [1]
The TFR in TFA appears to be much more ambiguous than this. I'm not sure they're really comparable.
Which specific series? Why do i need to know when sportsball happens, any variety of it? Oh, and concerts too. Why do i need to know when taylor swift is in town?
Nope, it is not nearly that simple, and consequences can be dire.
> SPECIFIED BELOW WITHIN AN AREA DEFINED AS: 3 NMR OF A QUALIFYING STADIUM OR OTHER SPORTING VENUE HOSTING A QUALIFYING EVENT UP TO AND INCLUDING 3000FT AGL. QUALIFYING LOCATIONS AND EVENTS ARE DEFINED AS ANY STADIUM OR OTHER SPORTING VENUE HAVING A SEATING CAPACITY OF 30,000 OR MORE WHERE: A. A REGULAR OR POST SEASON MAJOR LEAGUE BASEBALL, NATIONAL FOOTBALL LEAGUE, OR NCAA DIVISION ONE FOOTBALL GAME IS OCCURRING; OR B. A NASCAR CUP, INDY CAR, OR CHAMP SERIES RACE IS OCCURRING, EXCLUDING QUALIFYING AND PRE-RACE EVENTS.
I don't disagree with you that there should be no onus on pilots to have to hunt for this information (which is why I would guess that SEAMS is maintained, but not sure) - my point only is that this isn't really comparable to the TFR mentioned in TFA. All the Stadium TFRs are static; the "national defence" TFRs are not.

Isn't ATC going to yell at you before you enter such a TFR?
