Any and all help appreciated.

Is your exponential model based on a line of best fit or one data set only? I would recommend sticking to one data set as it is less time consuming and the use simple exponential model. That should make work easier... Not sure what else could be done but it did help me get 1st place at the ISO state tournament. :D Feel free to ask questions as I am happy to help. (Shame I ain't doing thermo this year...) :cry:

We did lots of data sets on various runs.

Hum. Ok then given that what you're doing is fine because it would help reduce error unless your standard deviation is too high...

You should be fine. I personally use logarithmic because I think it makes more sense, but as long as you can predict a temperature with it, it should be fine; given the amount of mishaps that can occur when running, there is no 100% accurate (in practical terms) graph.

Since I'm a foodie, I have my trusty thermapen to use. It's fast, accurate, but also pretty expensive. Best food thermometer I've ever used.
