My oval shaped Farberware has an "Automatic" setting that works like Auto-Shift, but I timed it (easily done because it has indicator lights for high and low) and it switched from the high setting to low after about 20 minutes. Barely long enough to get the cooking process started, and more like a pre-heat function. I think the HB cookers remain on the high setting for a significantly longer period before automatically bumping down to low.
