Yes, the water on coil helps significantly. There was another post in "Saving@Home" forum where I discovered the mystery rubber plugs on my window AC units... and the purpose of those is to hold the condensed water and the fan blades splash it to the condenser coil. When I plugged the holes I saw almost 10% power consumption decrease! This agrees with my measurements with central AC unit which current consumption I measured using clamp on AC current meter with Cool-n-save system operation and not.
