Your list of correctly spelled words that Chrome got wrong include eight instances where you list the same word twice and six instances where the same word appears three times in your list. To make it into a worst-case scenario, I considered plurals and preterites of a word to be the same word. Example: "splitter" = "splitters".

In reality, you only have 102 unique words in your list, one of which ("upgradable") truly is misspelled. This suggests that the Chrome spell check is only 83.6% as bad as you think it is.

So, do I win the pedanticism award this month?
