How can I create automation using bayesian sensor to speed up water heating to 85C?

I have electric kettle for water, setti, tuya local.
This kettle have option to set temperature to 85C for example for green tea.
But its manufactured that way, and its good, that when water temperature is approaching 70C, it slows down, turns off, waits, turns on, and loops it few times to not exceed temperature beyond 85C.
Now, I would like to learn how to use bayesian sensor in home assistant. So i think that good way to learn would be by practical example.
How can i control this kettle using bayesian sensor, which without slowing down heating will estimate probability of water reaching 85C faster?

If i turn this heater on without setting temperature, just for boiling, i can see that when i turn it off at 80C, temperature still rises to 96C.
Its probably water characteristics. Also all depends how much water is inside.
SO bayesian sensor could, when i just set to boil water, check how fast temperature is rising using maybe derivatives ? I dont know, and when probability that turning off water heater in some point of time, will be high enough to rise water temp to ~85C, do it, cut off heater from power.
Is it possible to do and how?
Thanks.
