TWO DEGREES
System overshoot is the room temperature that is way over the set room temperature from residual heat from the exchanger into the room after it has shut off. System lag is when the temperature drops below the set point on the thermostat.
If the the temp gauge is swinging around oddly the sending unit might be bad. Otherwise i would replace the thermostat cheap part, sometimes a pain to change but definitely worth the effort. YOu can check the sending unit w/ a volt meter and just change the thermostat for good measure. Both should be located in a haynes/chiltons manual.

The recommended clearance footage or "fall zone" for a swing set should extend a minimum of 6' from the structure on each side. The fall zone in front and back of the swing should extend out a minimum distance of twice the height of the swing as measured from the ground to the top of the swing support structure.
