Can HeaterMeter calculate time to reach the target meat temperature?

Seems like it should be possible to estimate the time for meat to reach the target temperature based on rate of temperature rise over time. Is this something that anyone has looked at. Seems like a prediction algorithm could get more accurate as the temperature approaches the target.

The heatermeter already shows rate of temp rise. You can't really depend on that number though because meat cooking is non-linear. When you see the graphs that show meat temperature it usually looks like the profile of a flatten bell curve (the first half of it anyway). The problem with predicting accurately the time meat will be done is that humidity also has a large affect on the cook and how long plateaus will last. Some cooks have multiple plateaus. You're best bet for predicting when meat will be done is experience.

The HM already does this, if you set an alarm for a food probe the HM will eventually start to report the estimated time to reach the target... but as Steve said, it is not reliably accurate due to all sorts of factors.
 
Yeah the problem is that the temp curve is two halves of an S with a long flat spot in the middle so there's no real way to estimate it. It does calculate a straight line best fit temperature ramp if you have at least 30 minutes of food probe data and the ramp is more than 1 degree/hr. The algorithm only considers the last hour of data to "ignore" that the graph should be more of a curve. This number is displayed next to each food probe's temperature in the webui. As Ralph said, if a high alarm is set, it will also calculate the time to get there based on the current linear increase. The number is sort of worthless though due to the actual temperature being non-linear.

Someone get to work on HeaterMeter neural net AI for temperature and stall prediction!
