Of course that maybe not so much of a problem with the much bigger pots in a pro kitchen. The full on/ completely off - regulation method is also not ideal for sensitive stuff like pudding or sauces. Even with the best cookware it heats up so quickly that the heat can't be spread over the bottom of the pot evenly.
None of these problems are present with good commercial units.
