Rank is pretty much your chocobo’s level. That’s the simpliest way to put it. As you acquire XP, your rank will increase. Every Rank increase will get you 1 Training Session and 5 Percent Points applied at random across your stats. At Rank 10, your chocobo will start acquiring racing abilities. At Rank 40, you can retire your chocobo for breeding. At Rank 50, your chocobo will stop gaining XP, meaning that Rank 50 is the max Rank.
Rating is the overall rating of your chocobo’s ability, and determines what divisions you are allowed to race in.
This is the real reason I’m writting up this guide. There is an incorrect formula floating around the internet about how rating is the average of all stats. This is very incorrect. The correct formula is long, involves a lot of ugly decimals and such. This is the simplier version formula though.
(Combined Max Stats/500) x (Rank+10) = Rating
Using the correct formula, we can see that ONLY Rank and Pedigree determines your Rating. Feeding your chocobo does not affect your Rating at all, meaning that all stats gained through feeding are purely bonus and put you above your opponents. Just another reason to feed, eh.
Also, using the above formula, we can see that the MAXIMUM RATING any chocobo can obtain is 300. For this reason, I expect R-300 to be the highest racing division. So, for all those hardcore racers out there, there’s a lot more to come.
285 RATING ACHIEVEMENT
Since we now know what affects Rating and what doesn’t, I’ve figured out how to reach this achievement and get the title ‘Chocobo Trainer’. Be warned, this is the hardest achievement to get in Chocobo Racing, it’s ‘The Final Witness’ of the jockey world.
In order to get a Rating of 285, you need a P9 Chocobo with a combined Star Rating of 17/20 and achieve Rank 50. If you have more then 17 Stars, you might hit 285 at Rank 48 or 49, but 17 Stars is the bare minimum in order to get to 285 Rating.
