True, but if you don't have a temperature-controlled processor and
are developing in a water bath in the kitchen sink then C41 is far
easier. With E6 the temperature has to be just right; with C41 you
can check the temperature after a couple of minutes and adjust the
time accordingly rather than aiming for a particular temperature at
the start.
