Not relying on an "actual thermometer" does not mean there is no compensation.
Sorry...thought it was implicit in my earlier message that there are brands promoting *software* compensation. When I read it back I realize that it was not clear that some companies either did not take into account, or they did so ineffectively, this variation in their HW design.
It's also interesting to note that some of them only recently added this. What was going on before they figured out it was necessary??
better to solve something with proper hardware design vs having to make up for a deficiency via software.
