No, sorry Sheri, you could always give it another try. I have used other "online" calculators as well but I like this one the best. There can be some confusion about the value to enter for the closing angle (.050 vs actual closing). Previously I was using a handwritten formula to find the actual closing angle but the P.Kelley calculator has a provision for this which I have found to be very close to the formula I was using. It just makes it easier and I'm confident it's accurate. I can toggle between static and dynamic figures while making adjustments which is helpful too. Also, I don't have to be online to use it.
