Well, one advantage of a cold oil drain that, I think, Mickey mentioned is that you don't burn yourself. So in the absence of other evidence, I would go cold. I'm not convinced that particles in hot oil somehow disperse out of the oil and cling to the motor walls. It sounds good, if you don't think too hard about it, but I doubt it happens.
Why don't you loosen your drain plug until oil is slowly flowing out through the threads until enough oil has come out so that you are at the middle of the sight-glass and from then on just replace the same amount as comes out?
I have two oil jugs. One is for dirty oil and one for clean. I pour the drained oil into the dirty-oil jug to measure it and then put that same amount of oil in the clean-oil jug and pour it into the bike.

From the first service, I've added 4.1 quarts, and... the oil is always fully above the level of the site glass. So far, no consequences (if I've indeed over filled), but, perhaps I'm adding more and more total oil volume each time I drain (less than 4.1 quarts) and then add back 4.1 quarts of new oil. I think I'll try cold next time, and allow like 30 minutes to drain.
Has anyone experienced a problem of overfilling? Will the oil "foam"?
