Leveling a FC rank? Any updated guides? Credit Requirements?

Been looking on google for this info. Only seeing 2014 and 2015 stuff really mentioned. One website seems not to list how many credits are needed for a rank correctly. (Example saying 2000ish vs the 4000 for rank 2)

So was wondering is there a new guide somewhere that talks about how many credits for what rank, plus all the ways the truely count for credit?

I saw HQ Gathering/Crafting/Fates for one. Leve Quest turn ins for another.

Guess looking for the good way to focus on things to get to the FC Plot of land ability at least. I heard so many rank up to 8 in no time flat. Thanks for any advice.

Expert delivery. It takes about 90,000 credits from start to rank 6.

Can be done in a day solo.
