Of course its just an estimate. I’m sure the “burn rate” will change between now and whenever it could be extracted, if that ever happens.

At the current usage rate, how long would 511 billion barrels last?

There is (admittedly anecdotal) evidence that it doesn’t, based upon the path travelled by the “loogie” that hit the Mets baseball player whose name I can’t remember.

They need to go with whatever system calls penalties consistently. So many refs call penalties differently based upon how much time is left in the game, or season, or presumably, how many fucks they have left to give. Maybe they already lost their bet, who knows? It would be amazing to know what PI actually is consistently.
