Here is the email response I received from Brandt:

Ron, the new and more advanced machine these days, Are their timer
movements and duration controlled entirely by a microprocessor and as a
result sometimes it might take a minute to move a notch and other times
it might take 5 minutes? In other words, would a notch in a cotton
wash function take longer to move as opposed to a notch in a wool wash
function? Or in your experience, a notch increment is constant during
a timed event?

By the way, doesn't Brandt sell their machines in UK? My machine is
French-made, but not particularly for the French market.
