What is the maximum percentage of production efficiency that can be achieved?

What is the maximum percentage of production efficiency that can be achieved? And how to achieve it? And for the example as Russian Empire. I only have 84% and for the most part this number is made up of certain policies. https://imgur.com/a/aZHVGKH

In order to truly minmax, you will have to form either Israel or the Roman Empire, as these are the only two National Idea sets that have a full +20% Production Efficiency in them. You would also have to flip to either a Peasants' Republic or the British "Constitutional Republic" government type for an extra +10%. You would need to be as high in Admin tech as possible, as various tech levels give a permanent Production Eff boost, as well as the +20% simply for being "ahead of time" in Admin. You'd also want a Parliament so you can pick up a temporary +5% globally from the "Conduct nationwide land survey" issue.

Idea Groups would be the big one here. You can get +20% from the Aristocratic-Innovative policy, +10% from Economic Ideas itself, and +10% each from the Court-Economic, Expansion-Plutocratic, Humanist-Aristocratic, Naval-Economic, and Trade-Economic policies. Unfortunately, that totals 9 separate idea groups, and all 6 of these Policies are in the Administrative category, so it's impossible to get all of them. If you can stack together two extra Possible Policies and/or Admin Possible Policies from various other sources, the combination of Aristocratic, Innovative, Humanist, Economic, Court, Naval, and Trade Ideas (the eighth Idea Group should be irrelevant) would be the biggest possible combination at +60 70% Production Efficiency overall (forgot the boost from Eco Ideas itself, derp).

This, of course, ignores various temporary or permanent modifers you could no doubt get from random or scripted events, mission rewards, Great Projects, and so on. And of course, local province modifiers can be even higher due to Workshops/Counting Houses, being Parliament seats, or having certain Trade Company investments.

As I recall, global Trade and Production Efficiency bonuses are capped at +200%. So aim for that, as it's pointless to go higher except to provide a cushion against random bad luck events that'll lower the value.

@Chatbot your overview was quite extensive. I appreciate it.

Personally, I'd much rather have goods produced, trade steering, or trade efficiency than production efficiency. The first three all increase trade income. Production efficiency does not. And trade is where the real money is made in EU4.

You're focusing on the wrong modifier if wealth is your goal, Faver.

I know that trading is much more profitable, but that’s not the point.
