Wow, you'd think that if someone volunteered their time to come up with something like this, people would thank him for the effort, even if they didn't like his formula. Then, you'd think the people who disagreed with the formula would actually suggest a formula - in the spirit of "hey what if you tried this - I think it might be more accurate", you know, as opposed to just proving they read the glossary of their statistics book. Those who can do, those who can't try to make themselves look smart by ******** about what others did.
