I did not fully understand what people meant by, "Accuracy over speed," until I began to try the instant death mode on this site. Instead of giving you a penalty for mistakes, or letting you hit backspace to fix it, this mode ends the test immediately and counts the rest of the unfinished quote at 0 WPM. Even though I feel slower, focused on accuracy, I still get my best scores when I'm able to reach the end of a quote in this mode.
