A couple of you really geeky types like me might enjoy this: I took a look at the data from two of my faster runs at ADSI on Sunday in the hope that while they were both similar, there might be enough differences between them to reveal some areas where improvement could be found. And I think I did. Here is the annotated version of the graph with MPH on the Y-axis and time on the X-axis:
The speed looks notchy but its being measured in small increments of time so ultimately that is to be expected. But hidden in here seems to be the fact that my slower run was actually mostly faster except for the very beginning and end of the laps. And that made the difference in times.
So it appears there is much yet left to be learned. Which makes me very happy.
