Why 60 nights.

A mouthguard is not something you judge in one night. Your jaw may feel slightly forward when you wake up at first, and that fades. Light soreness is possible in the first few days.

Sixty nights is long enough to mold it, start at neutral, try a step or two, and decide with a few weeks of your own nights. It is also why the guarantee exists: every mouth is different, and it may not fit everyone.
