Is there an easy way to show the rate of change(Delta) of the RoR? |

Please read the Quick Start Guide on setup and curves.

Just checking - do you really mean the RoR of the RoR itself? If so, that would more correctly be a rate of change, but no, there's no integral of the RoR and honestly I can't see its value |

I really do mean the RoR of the RoR. I was thinking about Scott Rao recommending the declining but steady decrease in RoR and how to connect to a PID. It seems the RoR of the RoR would be a fairly static (level) value and would require less adjustment. |

Well, in theory. Check the computed data to get an impression of reality. The amount of smoothing you need to apply even on excellent measuring systems will delay the signal that much that your PID will act much to late always. |

Here is a post that shows how to use symbolic formulas to compute the RoR of the RoR. This one use it to identify flicks. You can add a virtual device along those lines and have its curve plotted during roasting, but its noise will render this completely useless. |

Thank you. That seems like just the right post. |
