It's your last day on the job where you've installed a new system or replaced the boiler with a condensing boiler that has outdoor reset controls and it's time to program the high and low water temperatures. You've done this hundreds of times before with all different kinds of heat emitters in all different kinds of houses; you're a professional. Are you confident enough to know that you will nail it or are you more cautious and brave enough to start with lower water temperatures with the goal of better efficiency? Or are you the kind of responsible contractor that doesn't want any call-backs and wants to keep the owners happy, choosing higher water temperatures than what you think is necessary; to hell with efficiency?
