So, in general it seems the new kid characters tend to appear more often than the older kid characters but, especially Matthew. He appears more frequently, given his episode span, than any character other than Whit. Again, this information is... worth nothing. But, I thought it was kind of fun to compare different characters and make educated guesses as to which characters would be higher and lower as I was compiling the list.
