Loved many of your quizzes and thus subscribed. These sprinting quizzes seem to be getting more and more ridiculous. I guess there is a database of people who appreciate these; me aged 56, slow in typing am not one of them! I care and so I comment!
Well I'm 57, and I'm not the fastest typist either! You do have the chance to test your skills without having to hurry, though, because we try to make sure there's also a full-length version posted of each sprint quiz. I guess the point with the three modes - 15 seconds / one minute / full length - there is something for everyone, and each type demands quite different skills. The full length ones are genuine tests of memory, the other two are of how you can manage under pressure. For me, as a quiz-taker, I like the 15 second ones the least, and one minute sprints the most.
