It never dawned upon me to grade it in this format. But then in retrospect you'd have to readjust your ratings, if your 10 will always represent the best episode to date?
To me 10 should exemplify flawlessness. There are only a handful of such episodes in the Trek history.
Interesting. I’ve always graded based on enjoyment. Someone’s flawless ness might be someone else’s crap. That’s the flexibility of grading I guess.
