Letting someone down isn’t the same as missing a task
CRED covers letting a person down. Example: you said you’d shoot the game, and your partner ended up standing there alone with the camera bag.
Role covers missing your weekly tasks. Example: you owed three posts and only posted one.
Those are different problems, graded in different places. You never lose points twice for the same thing. If it ever looks like you did, come tell me.
