I need help

[Kitalrez]

So, I need help. (Ok, not that kind... although I wouldn't turn it down, I guess). I'm trying to max out the stats on my blue chocobo. She knows Bore and Treasure Finder already.

Stats are:
STR: Poor
End: Poor
Disc: First Class
Rec: A bit deficient

I'm on day 61. I'm using care plans to improve physical stats and then feeding zegham carrots to minimize the loss of Disc and Receptivity. So far, nothing's moved in awhile. Now, given that the current thinking is chocos have a maximum of 637 points to distribute in stats, and that the levels break down like this:

Poor: 0-31
Substandard: 32-63
A bit def: 64-95
Average: 96-127
Better than average: 128-159
Impressive: 160-191
Outstanding: 192-223
First Class: 224-255

How exactly would I max out my bird at Average, Average, First Class, BTA/Impressive? My suspicion is that since I'm past day 60, my stats have frozen already, but assuming I decide to run this experiment over again, how do I fix things so I'm closer to max? Here's the wiki page for comparison
