Perhaps the reason that some have suggested the lights blink faster as the
load gets higher is that the current range is 1s -> 2s -> 3s -> 4s and
that people don't percieve phenomenon under 1Hz very well. Perhaps a 
suggestion would be to start the blink at a faster rate at load=0, like
10 blinks per second, and get slower as load goes up, 9 per second at load 2
etc... to 1 per second at a load of ten and above.
