Any Spreadsheet interest here?

I was building a spreedsheet for myself to see the affects of a draw down on my retirement account. I made it simple to start with by using the 4% rule. I used the last 12 months data for the G, L-income, and L-2020 to see what would happen if I used the most conservative methods to withdrawal and earn at the same time. It is kind of neat to see the affect, but I have a lot more tweaking to do. If there is any interest in this, please comment. If you have any ideas to add to it, comment. Here are the screen shoot results.
