I agree that there is no performance gains in opening more than 1/2 turn and I actually never even thought about that one way or the other. That is not a manufacturer manual I have but rather a welding supply catalog from back around 1998 or '97. As I said from the beginning this has been discussed for as far back as I can remember and that's why I said several times in this thread that it is a matter of opinion and for everyone to be their own judge. One thing is for sure whether or not one takes the position of opening the valve all the way or only 1/2 turn the overwhelming advice is to go only with the 1/2 turn, so overwhelming in fact that I have found next to nothing to the contrary even though I took the time to search.
