The charts are neat. Are you using any insights gained from the data collection to guide your practice?

I'm not tracking my music practice (maybe I should) but I've been wearing a health tracker for years and have collected a ton of data. None of it seems very actionable because there have been no surprises.

These charts are serving a few purposes. First of all, it is motivating to me to see improvement. I can see for instance learning curve dropout when I skip practice, and knowing what a gap will look like on the chart motivates me to keep going. I also use the key-specific curves to choose keys to focus on, so that I don't keep going on the ones I know well. I'm planning to add some more visualisation to understand if there is a pattern to perhaps sharps or flats being harder, or if there is a sharp to flat transition effect which I suspect at the moment - after playing a few days where all the keys are sharps, it feels weird to move to flats.
