The first day she completes a test is considered the baseline, and is represented by 0. For instance, on the first day she did the flexibility test, her result was calculated as 0. On the second day, in comparison to her first day's result, she was able to reach 1 1/4 inches less than the first day, which was recorded as -1 1/14.
