Balmung Server (maybe XIV) First: Rank 20 Chocobo?

[MomomiMomi]

From level 10 onvards (after using first Thanvarian Onion) it keeps rewarding the same amount of the XP as at level 9 so you need more and more Krakka Roots for each level (it's about 0.9% at level 10 resulting in just over 111 Krakka roots for that level). So in principle - the XP gained by training is "frozen" on the last pre-onion level and as result the percentage goes down as the XP needed for each next level goes up. It's about 0.6% only at lvl 15 or so. The good news is that weekly Challenge Log bonus is still full 15% (5 + 10) of the current level max XP (note though that it shows as zero while chocobo is stabled)

But rank 9 is 12k exp. He said at 19 it was 18k (and about that at 11 as well). Which is correct?
