> I realised that induction responds instantly to any changes
Hmm... My electric hob seems to control temperature by the amount of time the heating elements are active (+presumably a thermostat). There's a red light when the heating elements are active (or hot but switched off), and a definite click sound when the heating elements come on. You can see the heat immediately turn on when you change to a higher temp, and when you change to a lower temp it seems to just leave the application of heat off longer (I guess allowing elements to cool down to whatever the thermostat says they should be).
