Personally, I think that isn't the best advice. Yes it will work, however if you use the 'set and forget' method you're guaranteed to have carbonated beer with minimal foaming issues. Set the keg to serving pressure and walk away for a couple weeks. Then you won't be posting here about how all you're getting is foam.
