The sentence, "The Australian platypus is seemingly a hybrid of a mammal and reptilian creature" is an 11.3 as it has 24 syllables and 13 words. The different weighting factors for words per sentence and syllables per word in each scoring system mean that the two schemes are not directly comparable and cannot be converted. The grade level formula emphasizes sentence length over word length. By creating one-word strings with hundreds of random characters, grade levels may be attained that are hundreds of times larger than <a href="/wiki/High_school" class="mw-redirect" title="High school">high school</a> completion in the United States. Due to the formula's construction, the score does not have an upper bound. </p><p>The lowest grade level score in theory is −3.40 (belonging to the passage "Go. See. Stop. Rest." for example), but there are few real passages in which every sentence consists of a single one-syllable word. <i><a href="/wiki/Green_Eggs_and_Ham" title="Green Eggs and Ham">Green Eggs and Ham</a></i> by <a href="/wiki/Dr._Seuss" title="Dr. Seuss">Dr. Seuss</a> comes close, averaging 5.7 words per sentence and 1.02 syllables per word, with a grade level of −1.3.
