Whereas I, l'shitati, hold that a mistake is a mistake, even after 3000 
years.  The people who were cutting off the ends of the brisket before 
putting it in the pan because that's how their mother's did it don't 
have to continue doing it once they find out that it's because the pans 
were too small.  The fact that many Rishonim and Achronim never saw an 
olive in their lives and had to use a guestimate for kazayit doesn't 
mean that their views overrule the actual metziyut of an olive.
