Why, when opening a cylinder, is it recommended to do half a turn back?

Actually the usual recommendation is 1/4 turn back. But the amount of "turn back" isn't really important. All you are doing is making sure the valve isn't jammed all the way open. This is bad for the valve. All you really need to do is 1/4 inch back. Just don't have it jammed open.Why, when opening a cylinder, is it recommended to do half a turn back?
I've never heard to turn it back half a turn....I've only ever heard to turn it back a quarter of the way. I certainly wouldn't be turning it half way back as it may not deliver air at depth (deeper than X feet). Personally, I don't turn it back a quarter of the way either and have never had freezing issues....though I also don't dive in super cold water.
