The spreadsheet should not repeat every process.
For each process group I do a TAB IN EXCEL, then I do not repeat the area, the process, etc...
If they are in a column I DO NOT REPEAT IT: this let me filter based on Whatever I want and see the dependencies.
So, my flash card are similar, but in my opinion, more usable and useful.
I do not print them. When finished I can read it with iPad excel reader, that makes the works as I've not to write it. With PMBOK vs 6 in the future i can modify on excel and continue reading on iPad.
