It somehow took me until now to find out that the whole 3 dB = double intensity difference thing is just an approximation, and that in truth having the "deci-" in the name of the word actually makes sense because the actual rule is that 10 dB = tenfold intensity difference. See: 2 ** (10/3) == 10.079368399158986.
I am somewhat disappointed in myself for not realising this earlier ):
