      I do the same - listen to the boil.

      Another way is:
      At 100% power, allow the still to fully equalize with 100% reflux.
      Note the still head temperature. Then, slowly decrease the power
      until the still head drops a bit. On mine, I can drop the power 15%
      (measured using a true rms wattmeter) before the temp starts to drop
      during equilization.
