I created a new thread so that the original thread discussion doesn't meander!
As you can see, both approaches are likely to work.
App #1] Looping through the range one by one.
App #2] Assigning a formula and converting it to values.
What I'd like to understand is:
What criteria shall a person (I don't consider myself a programmer for lack of skills) apply to select the approach out of these two? Do we have to test these based on time-they-take trials every time or is there any thumb rule to this (I am keeping out personal preference)?
Of course, I realize that the coding's end result shall be reduced human effort and accurate results.
