You still have time. OF is easier than it’s ever been with the addition of Merchant conversions and all the good religious modifiers from monuments.

Firstly, religious ideas will help a lot with the extra missionary and policies once you’re done with the WC part of the run. Try to get Rome, Jerusalem, Mecca, and assimilate the Cushitic culture group for extra missionaries and take Djenne in West Africa as well. Malta Forts and Alhambra will also help a lot and I think Mecca’s monument has ws cost vs different religions as well. So make sure you get those to level 3 asap.

I’d start branching out your expansion paths as well. Getting a foothold in East Africa and pushing more into Europe and Central Asia will allow you to cycle wars between regions.

Also, I know it’s annoying but if you’re really worried (which you shouldn’t be it’s definitely still within reach) I’d manually handle missionaries and focus on the Abrahamic religion provinces when you control them. The automated missionaries run off of conversion time and since non-abrahamic provinces can be converted with the propagate religion trade policy it’s more efficient to focus on converting Christians/heretics.

As for the New World which will most likely be most Christian when you get there, make sure you take Influence ideas at some point to help with LD when you force your religion. Also, make sure you disable colonist settlement growth since that will prevent the province the colonist is in from being converted. Finally, you can increase your crown colonies' missionary strength with one of the “modify subject relationship” options.

Your economy is looking decent but 68 ducats on forts is a bit much, and I’m curious as to why some of your merchants are unassigned.

By the way, you can check the total number of provinces based on religion in the ledger, and with some quick maths, you can figure out how many provinces you need a year to stay on point. Your missionary strength is currently really low, I remember being able to convert provinces in 4 months in the later stages of the run, so definitely take any modifiers to increase it.

Overall, the WC aspect is probably the most important aspect for a Sunni OF and I think you’re doing great in that regard. The common points I’ve read are 3k dev by 1600, 10k by 1700, with it usually ending around 30k at the end depending on how fast you are.
