Default 180 Degree Thermostat "Hunting"

I probably wasn’t clear in my post. My thermostat is located adjacent to the radiator (i. e., at the top of the posted picture), not adjacent to the engine block (which would be near the bottom of the posted picture).

Granted, the traditional place to install a thermostat is as close to the engine block as possible, to measure the actual engine heat as accurately as possible. However, with my current probe configuration, moving the thermostat to the bottom of the top hose (i. e., closer to the block) would make the temperature gauge be even more inaccurate, wouldn’t it? Because that would put the probe on the “cold” side of the thermostat.

I’d want the probe on “hot” side of the thermostat, correct?

The hoses themselves are not leaking—they are dry. In the picture, there is a small drop under the center of the upper tank. The stop leak has (most likely temporarily) stopped that drip for now.
