For ‘fun’, I downloaded my Google Fit data and then did some preliminary analysis. It’s very crude, but below is a heatmap where the correlations between measurements are over .5. The data, while mostly empty, does include activity (steps, workouts), calories burned, HR (min, max, avg), and BG. It will probably take lots more data, much better data cleansing to make it worthwhile. and I will take a look at xDrip and overlays, to see if that would be useful.
Some of the following is simple correlation of similar measurements, or spurious, but some might have value…
