Go 5 days or so without getting too many scenes with the other ponies. (I think 2+ means you miss the scene)
What do you mean by +2?
Like 2 scenes or more with the other ponies.(It might be when you reach 2 that you are unable to get Moona's scene but I'm not fact checking it)
I'll test this and let you know if it worked.
I spent 5 days working and then 6 days just reading, and nothing happened, so it seems you're right.
