Krystian @krystian3w this issue is for information only. I think you'll find this interesting.
I'm developing a variety of helper tools, still too early for prime-time, but this is a preliminary finding from analyzing my hosts repo history.
The data here has the granularity of my commits, whose frequency has varied over the years.
This bash file is what I used on my repo to get data. This is easily adaptable for your use; feel free. I use Mathematica for the plot, but many other things can produce graphs like this from CSV data.
