Continuing the 31 Dec 2001 - 9 Jun 2002 log of ^z weekly (weakly!) miles in JogLogFog (9 Jun 2002), the scorecard for 10 Jun - 6 Oct 2002 in raw form looks like:
|M +||T +||W +||T +||F +||S +||S =||Total|
... a forest of digits, of minimal interest except perhaps to the person who pounded the pavement for those distances. But put into a graphical form it becomes a bit more comprehensible. Here are the ^z daily runs (inverted red triangles) along with weekly totals shown as 7-day (green) and 30-day (blue) lagged moving averages.
There are some interesting phenomena visible, including troughs in May (muscle & joint soreness, perhaps from running too far too soon) and July-August (sultry weather & bad air quality), as well as a steady trend upward in peak distance covered during jaunts.
But much more can and should be done to process these data, remove "noise", and analyze "signal". This is a splendid example of a filtering problem, for which science has developed powerful technologies over the years. But pending that discussion, a fistful of memories from ^z runs of the past four months:
