Steve, if ever I have an Excel question, you are definitely da’ man. I am watching your video and the thought that you put into this tool is amazing... Thanks for sharing. Danny Question- at 29:39 in your Helps video, how are you calculating 449g for the total water in the soaker? What am I missing? Steve Petermann Hey Danny, The last 20 years of my engineering career I did mostly software engineering including a lot of Excel applications for my boss so it was a lot of fun for me to work on this. In fact, I was kinda bumbed out when I ran out of things to add to it.
