From some mails asking "what is clue #2"

That is the clue lol. Think about it carefully along with clue #1. I in fact chose these numbers because they are 1) accurate, but relate to each other in the form of an equation. (don't think too deeply on that last part)

As for the guessing.

You send me all 3 guesses at once! As long as one is right, you may continue.

So far 2 people have guessed one number correctly, but based on clue #1 it was fairly obvious.
