1~10: Could not take any more than a few sips. Poison.
11~30: Could finish the cup, but would be strongly against my will. Garbage.
31~50: OK, but I regret my purchase.
51~70: Average, alright teas.
Would buy again beyond this line
71~80: Could enjoy and appreciate the cup.
81~90: Savoured it to the last drop.
91~100: Could possibly be living on this stuff. Elixir.
