There are dozens of spreadsheets. Everyone uses something that fits their way of thinking and their layout. There is not a single spreadsheet that fits everyone. I have collected a number of them to look at from various forums and built my own. Here is mine, there is nothing secret in it and notice that I am up to version 3 for this year. I almost always change things as I am building props or reconfiguring where props are in the yard and what controller they are connected to. That is why a spreadsheet is invaluable.
