Any and all of the developers listed at the bottom of your message are more effective and more reliable, and most are published formulae. Just calling a spade a spade.
I'm all in favor of calling a spade a spade.

Some of the developers I listed are open literature published formulae - others are proprietary. "more effective and more reliable" depends on the application and the results obtained, IMHO.
