The point of this table is.... Repetition and Absorption.
he started this chart years ago, didn't know about scopes, Now different people learn in different ways, he learns in a visual way
so as such he goes out and researches each scope, he decideds to make a spreadsheet with parameters / features of scopes.
he then compares them and see what scopes have what and what don't,
This is his way of digesting the information that needs to be digested.
AS A FACT, i used to the do the same thing when it came to Engineering formula's , I would first do it manually, but then to absorb it
i would create a spreadsheet and i would find that the constant re remembering of the formula would cause me to learn it and the mathematical
programming of it and repetition of other formula's would cause me to understand the formula in depth and what it was doing.
In terms of learning about scopes, for someone to create this spreadsheet is superior to doing a google search
