Second round of Hx: secret?

In several of the playbooks it says for the Hx that when someone tells you your Hx with them, instead write down n because of a reason.

Reasons like "Choose the character you trust the least. Whatever number that player tells you, ignore it; write Hx+3 next to the character’s name instead." (Battlebabe)

I get that when you're giving out the history on your own go (first round) you're setting out the fiction between you and the other player. "Remember that one time we layed siege to ... Hx+2 from me to you!", but is the instruction "ignore" rather than "change" because you're silently doing it?

Or do people say "Nah, I trust you least - I'm giving me Hx+3 with you..."

Say it out in the open, definitely! Makes things more fun.

Definitely should be out in the open... allows for all kinds of MC questions...

And just because the players know, doesn't mean the PCs know!  *laugh*  "Open secrets" can make for some awesome dramatic irony in play.
