so, I added a ton of work into this, and think I have made it better.
Instead of showing you data at a fixed time (like FPS last time it redrew the label) I show 0th to 4th quartiles: https://en.wikipedia.org/wiki/Quantile#Even-sized_population
This means I sample every frame, and display the lowest, highest, median, 25% and 75% values during the sample interval (defaults to 2 seconds)
So I have a question: Does all that make sense? I think it's a great improvement but if it's too weird/unintuitive people won't like it.
