Lots of tables...is there an assumption that some adventures will not generate treasure or injury for instance?
Page 2 and 3 respectively show the tables ;-)
The answer is yes, some adventures would cost more than they generated, or be a dead loss, some adventures would not generate any injury worth noting - personally I'd ignore hp damage on the assumption that it would be healed by the next action anyway, and only note "serious" injuries but that's personal choice, I don't like tracking HP of lieutenants...
The system is fairly flexible, leaving the decision of what is a good investment, what is a poor outcome, etc open, but the idea was to give players some idea of what they could expect. There was a reasonable amount of comment when it was discussed on BR.net.
