Thank you, I didn't even think about it like that. I guess you can't fluke mastery.

Its clearly me who needs to adjust. I don't think I have overly high expectations, but when you're used to seeing certain scores and then all of a sudden they drop, it sends up a red flag. I also have one that has really struggled, so I'm on extra high alert.

I'll just let him carry on. I feel a lot more at ease about it now, thanks!
