Thanks -- you can bind my wounds then, because as you see, Steve has
shot me down!

UNLESS -- *puts on Gilbert Gottfried voice* -- JKR uses the Lexicon
ALL the TIME, right? Right? So at some point later on, she used
Snape's too-young age from the chat, which she found in the Lexicon,
to determine what Sirius's age would have been when she sent him to
Azkaban! Yes! The whole thing is a circular chain of cause and effect!  

Either that, or she subtracted wrong!
