So implement MEIOU's mechanic where distance from capital affects autonomy?
This is very silly and ahistorical.
The English crown had more direct influence in places like South Africa, the crown colonies on the Eastern Seaboard, Australia, Calais, Gibraltar, Malta, etc. than they ever managed in Northumbria. Nor was this uncommon.
States routinely retained much greater direct control over their borders than their interiors. Something about the fortifications and armies being there seemed to make it harder for the local nobility to defy central control. Certainly the effects autonomy, like sailor and manpower generation per unit of development, were, if anything greater the further from the Capital you went historically. France, for instance, had the overwhelming majority of its sailors coming from its most distant ports in wrong culture regions. The Russians recruited far higher percentages of available manpower out on the steppes than they ever managed near Moscow.
Even if we bought some distance : autonomy relationship, the game is extremely poorly setup to model it. After all, oceanic distances were wildly shorter in this time period than overland. Spain could more quickly get new orders to their North African holdings than up into Basque country. The Ottomans had better control over Crete and Cyprus than the main population centers in Anatolia. Sailing was quick and the government could show force easily with a simple naval visit. Overland distance is easily 10x worse.
The real limits to the Ottoman prowess were the speed it took to move armies off the Danube and its tributaries. Once they lost naval supremacy at Lepanto, the Turks were largely constrained by how quickly the could transit along interior lines. Had the maintained unfettered transit across the Aegean, Adriatic, Black, and Mediterranean Seas, they likely could have managed far more territorial conquests.
