How much do you give away about the composition of your forces if you publish your pay scale and your overall monthly expenses by division?
A lot of people would say 'approximately nothing'. After all, the same monthly expenses could be the product of three eighth-circle spellcasters on contract or two seventh-circle on contract and two in uniform at seventh, or just of eight hundred men with no spellcasting power, and there's no way from merely the published numbers to guess which, so it's probably fine.
To be clear, Marit isn't sure it isn't fine. He just does not remotely trust the line of reasoning 'well, I can't think how I'd figure it out just from that, so it's probably fine'. In his experience people end up sort of mentally handicapping themselves, when they try to answer a question like that, asking 'why wouldn't I be able to figure out the answer' and coming up with all kinds of reasons instead of 'what other pieces of information which I might be separately able to learn would be necessary for me to figure out the answer' and therefore conveniently not noticing that the relevant other information is available, or at minimum that no one has been treating the other information as secret and so next month someone might make it available for some unrelated reason.
Marit has tried to teach a lot of people to notice this sort of thing, mostly without success. He has at least succeeded in teaching them that he'll yell at them if they share a lot of information because they couldn't think of a good reason not to, which is perhaps the most he can ask. He spends the rest of the day and the night combing with Pereza through the Shining Crusade's budgets trying to figure out what you'd need to know in order for these numbers to be useful to you. It's inferrable, probably, in which months they pay the High Priest of Pharasma, and approximately how their men are divided across the war's present fronts; it's probably not inferrable precisely how many seventh circle wizards they have, even less so if they report the numbers to the nearest thousand solidi.
Eventually he approves a plan where they'll report their pay schedule and the overall spending on salary, precisely, and salaries and expenses by division imprecisely, with assurances that the budgets across all divisions add up correctly while they may not within any individual division. He refuses to certify that this doesn't tell Tar-Baphon a lot of valuable information; he can't think how it would, but Tar-Baphon's smarter than him, isn't he.
