Steno Progress Graph

Now, this is a pretty sight, posted on r/Plover:

How fast do self-learners learn to use Plover? TypeRacer might be a good source of data to answer this question.

Via automatic scanning of TypeRacer activity, I found 23 Plover users who had recently used the site. Of the 23, many had just a few races completed, didn't evidence progress or regular usage, or had not logged races before they were proficient. Only six fit the profile of users who had used the site frequently over a period of 25 weeks, starting at a point when they were still getting average speeds of less than 60 WPM.

The graph above shows the median speeds of these six users over their first 25 weeks on TypeRacer in week-by-week windows. Weeks during which a user completed less than 10 races are not graphed.

Of these six users, only four have been on TypeRacer long enough to represent data points for long-term improvement. The following graph shows the median speeds of these four over 2-week windows for longer time periods, up to 125 weeks (a little over 2 years). Highlighted areas designate interquartile intervals.

While limited, I hope this data helps to paint a better picture of how quickly new learners can expect to get "up to speed." I think the conclusions are favorable; maybe someone will be emboldened to give Plover a try. If you want to conduct your own analysis, you may download the data I collected in the form of an SQLite database from https://mat.uc.pt/~mat1617/steno.db .
