In my new scale, °X, 0 is Earths’ record lowest surface temperature, 50 is the global average, and 100 is the record highest, with a linear scale between each point and adjustment every year as needed.

At least that follows some mathematical logic. Mohs scale of hardness is pretty close to pT scale in that sense, but there’s no mathematics or logic involved. It’s just a list of standard materials that define specific points on the scale. When you compare the results with a more logical scale, it looks neatly non-linar at first glance, but the closer you look, the less sense it makes. It’s just a list of exceptions to whatever rule you may have had in mind.
Doesn’t mean it’s a useless scale. You can totally use it for qualitative assessment of hardness, but steer clear of it when numbers and decimals actually matter.
