This is looks like a different approach to a tool I also tried to address to answer 'how much time should you invest in training' https://kerryjones.github.io/sharpen-the-saw/

Had a whole article that went into this: https://medium.com/hackernoon/how-much-time-should-you-inves...

I like the idea and it's certainly more detailed than mine, but I think some explanation of how this should be used and context is important.
