I think what he's getting at here, is that "because everyone else does it
this way" is not a very strong reason.
I get this frequently in engineering meetings, and I see both sides of the
On one hand, if a lot of people do it one way, there may be a good reason
On the other hand, it's a lazy attitude, and I've seen many cases where the
way something is usually done is not the best way to do it.
I think he's looking for you to present him with a "strong" reason for
The only one I can think of is that it dosen't have to be calibrated to the
individual thermistor, like a table would be, for maximum accuracy.
