Filter: 3Bet Size

I am creating a bunch of notes and I'd like to experiment with bet sizes.
The easiest way for me to do it is using the filter "Preflop Bet Sizing > 3Bet Size > Multiple of the 2Bet Between ___".
But I'm not sure how it works.
For example, if Cut-Off open raises to 3bb and Button 3bets to 6bb.
Would the "3Bet Size > Multiple of the 2Bet" be exactly 1? Or would it be 2?
Is there any difference if the 3bet (or 2bet) comes from the blinds?
Can anyone explain it?
Thank you.
