The progress reports are incorrectly calculating average speed. For instance, I ran 52.53 miles last week in 6:59:08, which is 7.5 miles per hour. However, the progress report states that I averaged 7.3 mph. It has generated this average incorrectly because it is taking the average speed of each run without weighting each on by their time. Alternatively, the software could just calculate distance divided by time for the entire week to get the right answer.
