Typing speed with exponential smoothing factor derived from decay_duration $it seconds as
`alpha = 0.5.pow(time_since_last_typing / decay_duration)`.
Last speed (typings per minute) is computed as:
`V_last = 60 / time_since_last_typing`
And resulting formula:
`V_avg = alpha * V_avg_previous + (1 - alpha) * V_last`
Note: it's an alternative for moving average for time series. The lesser decay_duration the bigger weight recent typing speed gets in the averaging.
