If you keep saying that 100.1 and 104 is the same, I'll start arguing that 104C is a minimum so the temperature could have been 120C most of the time. That'll make for a few pages of debate.
It will only be debatable for people who nothing about thermometers, and people like you who make up stuff and are unwilling to look up the specifications for industrial thermometers. Any on-line equipment guide will show that errors are typically 1 to 3 deg C plus or minus, depending on the type of thermometer and the range of temperatures it works with. In percent terms it is usually 1% to 5%. Here is an expensive one I just looked up in another discussion thread:

1% supposedly. 1.8 deg C plus or minus. That's quality.
Of course you can always use the set screw to make one several degrees too high or too low. But assuming Rossi did not diddle with the thermometer, there is no chance 103 deg C is actually 120 deg C. Not unless the instrument is rated for 0 to 10,000 degrees or something like that. (I wouldn't put it past him to diddle with it or use the wrong kind.)
See, if you had any idea what you are talking about, you wouldn't say this stuff. You should spend a moment learning about thermometers before commenting. You should have learned this stuff in 6th grade. In 6th grade they also teach that kitchen pressure cookers got a lot hotter than 100 deg C. You seem to have no knowledge such elementary physics.
