Started adding some new features that I've been thinking about lately. I'd previously combined the batch timer display with some other secondary displays and changed the range timers to something with more information density. Now I'm thinking that multi-range display could sensibly be extended to include various other kinds of batch statistics where it's useful to show that separately for different parts of the roast. The easiest way to add that looks kind of ugly, but I'll make it work first.
The first thing is average rate of change through the range. Very easy calculation. The other thing that I'm thinking is percent breakdowns which nobody should be doing with roasting data, but I've had some thoughts on how to make those metrics less trash so I'll implement a couple variations on that and see what users think about it.
