Wind-mark-up is undoubtedly better because it requires fewer steps than wind-mark-down (it's a direct method, as opposed to iterative, if we want to be pedantic).
The reason why people still use the wind-down is because they've been taught so by other people who had been taught so by... [repeat at will]. It's not a coincidence that on the Air Pilot's Manual the wind-up is presented first, and
then, for completeness, the wind-down is included.
Remember! Smart people use the wind-mark-up, the others just keep jiggling the wheel
