The small-small method gives the max amount of chain
if the chain wrap is adequate. If not, and you size with the big-big method, the drivetrain will have enough chain that it's overly slack in small-small. But most people prefer this latter compromise... I remember one gravel ride where the rider said "I just won't use big-big" at the start, and jammed his drivetrain badly on the second steep ascent.
