I really feel like I'm missing something. If you're ignoring the first note everyday, then I'm assuming you can't feed it during the day at all.
So unless there are actions required on specific days - there are only 11 combinations ranging from 10 night feeds to 10 no feeds.
If you don't feed it for 6 or more days you get the Flesh end. 5 Nights and 5 no Feeds got me Mirror. 9 - 6 night feeds got me Back Again. Then feeding it at night for the 10 days got the Transformation.... Help? T_T
