What do I do if I listen to a stage less than another one?

[Benjamin]

I am on a 6 stage (currently on 4) program and I didn't really miss a whole day but i did listen less hours than other stages.

Do I just listen for another couple of days after the 32 days to compensate some hours before moving to stage 5?

Do you mean you've finished the 32 days now? If you haven't you can simply add some extra hours to other days.

Usually if you miss a day you want to add x1.5 to what you missed.
