True wpm/cpm

[KitKat20255]

Already posted this ideea in discord, but this might be the better place for suggestions to be seen maybe.

When training your typing, sometimes you might practice in modes like ZEN, where some tests are much longer than others, And let's say for example, i do a test with 100 words at 50 wpm and i quit until the evening, then in the evening i have a long practice run of 5000 words at 60 wpm. Currently the average daily wpm would average between the two, and say it's 55. But I believe the true wpm would add all the words, 5100 and divide by all the time 85.33 min and my true daily average it's 59.76

I think both averages can be kept, with different names. For all the available timeframes, day, week month so on.
