It isn't that bad, exactly, and is still much better than thermostat control. I can see why these values were chosen - it is to try to prevent overshoots, but also to ensure that recovery is as fast as possible. Personally, I don't care if it takes 30 seconds for the brew boiler to return to the set temperature instead of 10 to 20 seconds, I just don't want to wait for an overshoot to cool down.
