Imps, Pouches, and Secret Recipe reward list

So are these scenarios possible. I've never used the juke box before.

1. It's at 500/1000 fullness and you use the jukebox. It will fall asleep for 3 days. If you reset the jukebox, it will wake up. When it reaches 1000 fullness, it will level up

2. Same as #1, except it's at 1000/1000 fullness. Also note that it needs to sleep for 21 hours, so will the juke box act as a pseudo alarm clock or will it pretend the 3 days never happened and continue to sleep the remainder of the 21 hours

3. Does the juke box have a cooldown

1. Not sure if you can force it to sleep without been full.

2. I'm pretty sure that since its only a 3 day bonus sleep time if the jukebox is reseted before the 21 initial hours have passed it would be like nothing happen.

3. Since it doesn't give that big of a boost I think it doesn't.
