You are mistaking accuracy for resolution. If Compunurses were accurate to 0.1C then noone would use thermocouples

The accuracy of a Compunurse is no better than +/-3C. You can't just measure the temperature of water at 1 temp; need to calibrate.

Problem with compunurse is error in remounting it each time, and the issue of where on the core to place it.

Temperature compression is an issue with any probe that is not directly measuring a temperature.
and you're right, resolution is not the same as acuracy, that's a good point. It's misleading to see a device show temps with changes by +/- 0.1 deg, when it's not even that accurate.
