How much Panache does a Swashbuckler / Kata Master Monk have?

As the title says. I've been trying to find an FAQ or anything on this for a while and I've come up with nothing. I've seen the little sidebar on the SRD that says some mess about the pooling of Panache, Grit, and Luck, but it doesn't say anything about sources.

It looks like it's the same feature, so it wouldn't stack - you'd just get charisma once to the pool.

aye, avr
