OK. I'd like to add a few thoughts and even criticise a little, but of course, generally, in my opinion - this post was fantastic.
Great idea, great work, a huge amount of useful knowledge.
1. Merchants in CoT's
You wrote about Venice: merchants cost: 15, income: 17,5.
Shouldn't it be 12,5? 250*1/20 is 12,5
But that's not the point.
First of all - you must still remember about Trade efficiency. In the begining, a lot of countries have trade at ~25%. And than what with your calculations? You should consider it in your compendium.
That it's:
Venice 250
Sending 3 merchants: 15
Year income: 12,5*0,25=3,75
Kicked away after ... let' say one year.
Loss=11,25
2. Morale
As someone said, rebels morale relates to your. And, you must remember, that it takes some time for troops, to raise it to maximum. Have you got enough time on MP, to change sliders, control rebels, attack in proper moment, than change slider again ...
3. Inflation
You seem to be very experienced player, so maybe it's a bit incautious to get into discussion with you, but <someone else wrote a little about it>:
In my opinion, it's also not very wise to keep treasury income at minimum for almost all the time. I think, that efficieny graph of inflation/income slider is someting like a hill, with light (but still) growth from 0% inflation to it's peak, and than steep fall.
Why? INVESTMENTS is the key word.
OK, you've got 0% inlation, but what for you need it, if you've got no money to buy your cheap facilities???
Which is better? To have 1000G minted and have to pay 333 for fortress, or to have 120G minted and pay 250 for fortress?
OK, in long run IT MAY pay, but remember, that in MP noone will wait centuries for you. It's better to have 50k solidiers, little cash, but defend your kingdom and than expand a bit, than have 10000G "invested", 10k army, and get ass kicked.
In my opinion, you shouldn't be afraid of using treasury income slider. Just - don't mint usless money. Use it for expansion! You'll have inflation on 30% level, but three times as big country. And you'll have a lot of fun from the game
4. Last, little though.
How do you want to have money for colonists, manufactories etc. without minting money?!?!
Of course - peace resolutions, merchants income ... but that's just not enough.
PS. Sorry, my language might be a little simple and my sentences not perfectly clear

Sorry for that, I hope you'll understand my point of view
