I've disagreed with the "granularity" theory of his in that I find that such systems in general are very clunky.
The only thing I liked about granularity (if I am using the word correctly) was the ability to have the computer code. Way back when Logician Internet before it became Medscape Encounter and bought by GE, the coding feature was extremely useful. You can't have that witout a drill down approach. But, the trade off is the speed. It takes forever to chart like that.
