The NES said he was submitting another FAQ on the topic (note that he does not write the FAQs).

Also note that the test he used at Solon was exactly the same test as his sample test on Soinc.

He has input on FAQs and rule clarifications, but it is collaborative decision as it is for all events.

Yes, and seeing as his reasoning at Solon was that the SHH equation was created by manufacturers for individual probes, when it is actually an equation that relates the resistance of any resistor (not just thermistors) to temperature using three points, I doubt he’ll get his way.

I guess the logic there is that most thermistors are provided with a data sheet with values that could be used to create a Steinhart equation, but these would be fairly inaccurate once you take into account the insulation used and general error. It's better to take your own data.

It sounds like it would be rather challenging to determine with certainty whether or not a team was knowingly using the SHH model. I could imagine a team independently coming up with it.

It might be helpful to note that we went over our design log with the NES at Solon and he looked at our equation, which is just a Steinhart model based on a few thousand data points we collected displayed in the form of a graph. He seemed to have no issues with it, and even asked to keep a copy of our design log as an example.

With a few thousand data points, a direct LUT or linear interpolation will work beyond 0.1 degree C.
0-75, 751 points is already 0.1 step size.

You can wrap your calibration with just another layer of on-site calibration with their thermometer for state/national.

what does “function graph of mathematical model supported by the data overlaid on scatter-plot of the data” mean? thank you!

Make a graph of the equation over the scatterplot. Not just a line of best fit, your equation that’s in your code.
