Penchant for beating dead cows much?
p.s. the documented spelling for 'the word after 800 in your last paragraph is 'line', no 's', please make a note of it. If it wasn't used as an adjective phrase for the next word, then the 's' would be appropriate. Guess we all can make spelling mistakes -- though as I stated earlier and you ignored, the word in the dictionary is spelled notational. The fact that the author misspelled it is a "UI" bug (i.e. the user-interface to the function causes confusion due to word misspelling or non-standard word usage).
