Description
It would be good to have a live stats calculation (namely of wpm). This live stats would be rolling limited to custom sized stack (FIFO). There must be a smart way to prevent spikes when calculating with rolling values (https://en.wikipedia.org/wiki/Moving_average#Cumulative_average).
When pause is triggered, the live stats should also be paused and display the last value before the pause.
For a "normal user" there would be a ramp up when resuming. This will lead to a sudden drop of the live stats values.
This is okay but maybe wait till the stack has sufficient new values after a resume to make the user not feel bad because he had a ramp up.
Live stats should never be persisted directly because it would explode the stats-file-size even more.
