Here's an updated diagram. Thanks everyone for the patience and the highly constructive feedback. I've made modifications and brought in more ranges to avoid being overly prescriptive.
As others have noted about ristretto, normale and lungo. I have seen that sliding scale and have resorted to referencing a La Marzocco article. https://home.lamarzoccousa.com/brew-rat ... und-world/
They also had a nice diagram that I incorporated.
Hope this helps other home baristas the way other charts have helped me.
