Why is everyone enamored with explaining their Skritter exploits with math? Are you all secretly mathematicians?
Numbers do not explain, much less capture, the nuance inherent in language.
As an example, using numbers, the English word `have` has 38 different definitions in my dictionary. The word `got` has 63.
Chinese is the same way: many words or characters have multiple meanings depending on the context. By bragging about how many characters or words you have `remembered` you only show you have a superficial understanding.
Caveat: I have the vocabulary of a small child in Japanese.
