I actually think I was the one originally asking to add that column on your dashboard I used to produce this graph
Might be, my memory is not what it used to be.

Sorry, bad quoting, I was referring to @ddmrddmr message regarding his addition to the dashboard.
I recall I asked that column because I wanted to produce those graphs for my overview. Now that I have suspended the usage of that column, it might be nice if you go on with it!
