For certain customers, being a little more comfortable is not enough.  We have one client that pushed us in our design of his tennis court cooling system:  we ended up with a state-of-the-art super high-pressure (2000 psi) stainless steel system with ultra-purified water—all run via a low (700 psi), medium (1300 psi), and high-range (2000 psi) remote control.  This enables “Mr. Tennis” to play in optimal conditions all summer long (after previously having given up on tennis for the summer months!).
