I have never heard the statistic that 75 percent of the shooters loosen the plug a bit after tightening it, (nor do I know how one would get that number), but I don't think it is the right thing to do.
For me triple 7 seems to make the plugs come out the hardest.
With the plug backed off - or less than snug, if the gas can find a path to excape between the shelf and the nose of the plug - gas cutting is a possibility...
