I guess C 5 would be closest. I agree about cream vs milk. Never milk ever and no sweetener."Coffee-flavored milk candy", I'm told, lol. So C3 or maybe C4 (which I think is the same as D2 & 3 and E1 & 2?), if it's cream and not milk (cream is "stronger"; milk waters it down too much).
My husband is a non coffee drinker... He does diet Mtn Dew instead!How do all you none coffee drinkers even function!?
As for the chart, anywhere between D, E, F, 4, 5, 6 would be fine
