I don't actually bring a BB wrench with me when I travel, so the belt is only tightened to as tight as I can by hand, which is about 40-45hz. Like you say, lower than their recommended amount, but 60 is really tight.
Never really understood why they want it so tight as that would introduce additional friction and wear on the BBs.
