@lanx0003 this is better than what I expected. I am learning a lot from you. And this is exactly the direction I wanted to go: to translate raw and scary numbers to adjectives and comparable rankings that beginners can use to educate themselves and make somewhat more informed decision, try speakers with more confidence. So, in short, yes, absolutely, I want to explore it further with you, properly credit sources and contributions and expand my database with more useful features.
I am getting my head around what you wrote and how I can use that data.
