Basic furnaces (including both original and current models used in Escapes) are just on-off, so it doesn't matter how high you set it - it won't blast at any higher rate of heat output. Since they may not be calibrated accurately, I agree that sometimes it makes sense to just set it high and turn it to the shutoff point that way.
Once the temperature hits the setpoint, the furnace will cycle on and off, regardless of the thermostat type.
