I'm looking at the wording, and as worded it seems that you get +1d6 damage per hit, applied per each unarmed strike within a fob? It says:

When you hit a target with an unarmed strike and you have hit that target with an unarmed strike previously that round, you deal an extra 1d6 points of damage to that target.

So that for each hit after the first, when you calculate the damage of that hit, you deal an additional 1d6?

And then for jabbing master, what it does is increase it to 2d6 on the second hit and then 4d6 on each hit after the second. Am I mistaken in thinking you can change the targets of each hit of your flurry of blows to hit essentially as many targets as you get attacks with your flurry? So that really, you're calculating damage on the go, not after rolling all hits, and thus you would know before choosing who to attack next whether your attack had already killed the target, and wouldn't 'waste' any attacks on them after they were dead?
