1st setting:1 Deep Green.
2nd setting:9 Deep Green
3rd setting:10 Deep Blue
I got the feathers changing message on everyone feed from the 2nd and 3rd settings. I also fed them all straight in a row, directly as the new 6hr window opened.
2nd setting he turned Honey Yellow.
3rd setting he turned Meadow Green. ^___^
Now to try and get a Turquoise i'm going to use 5 Deep Blue. But first, i'm going to go to the Ancient Forest and get Slash-All Materia before Disc 3. :D
UPDATE: Woke up to Turquoise this morning ^____^
4th setting: 5 Deep Blue
I suppose my calculations were correct and the RNG gods blessed me. Also, I got the feather message on the 2nd-5th berries, but not on the first berry this setting.
I did get my Slash-All Materia and plan on using it like Zelda in a new grass field :D
