Chocobo Companion levelling speed: Is it fine as it is?

[Dustytome]

you can feed it up to 48 times per day, when you stable it

each training session grants it 0,5-1%, so even rank 19-20 could be achieved within 4 days without doing challenge log nor killing a single enemy

You just have to completely kill any semblance of a sleep schedule and be exactly on time for those 4 days while also having someone else or an alt be always available to also train it. Realistically you'll probably only be training it a handful of times each day.
