mrtew,
As someone who has done some development myself, I can mirror Jim's comments that you can estimate 8 hours to get something written, plugged in, and working in your program. Then you start working on it and maybe you have a breakthrough and you get it going in 1 hour. Sometimes the d*mn thing takes 24 hours or more. Programming, like any other art form, is very unpredictable.
Just punch in your e-mail to my website at

You'll get an e-mail when there are major updates such as a web chat, release of the freshwater or any news on the saltwater.
