Maybe you are right Alan but I am sure that there are some bugs in the calculator.
There is just one owner/developer of this site, Andre Massow. He has been difficult to communicate with. This is due to a huge work load on his part.
I am hoping that he will communicate with us more as time progresses as I think we could help him pinpoint and therefore fix some of the problems that he is most likely unaware of.
Plus, of course, I would really appreciate his support at times.
Still, I am very appreciative that he is providing and supporting this site, and I want to try and do right by him. Hence I would like to use the site tools as much as possible.
