To whoever controls the spreadsheet :
You need to put more strict rules on data gathering.

The first "proc" message saying new feathers will grow just mean the chocobo will change color, not that the previous fruits were uneffective (just were not enough). But the following "proc" messages in the same feed are NOT valuable info ! They are just saying after feeding again, color would still change (you can go back with multi fruit feeds).

If you want to truly have serious experiments, you need to WAIT 6H after the first "proc" message before doing anything else, and report color change and fruits fed (which fruits, number, order even if I doubt it matters in most of the cases, etc).

If you don't apply these experiment rules, the spreadsheet is not better than the previous one you were disproving ^^
It requires a lot of patience though, but it'll bear the most valuable information we can get to map the square-enix wheel of colors and the effect of fruits on it.
