Well, that's true. In this case, however, testing with novice users isn't exactly critical. The target audience here are repeat users, after all, so learnability is probably a lower priority than raw performance for a regular user. That means that the devs themselves could have tested, and I sincerely doubt that they would find the scrolling odometer faster OR more accurate than keyboard entry.
