I think the end result is that I'll use some computer calculations but focus on my weekly planner log. A two page spread opens up to a week where I can glance and see my activity, note feelings of fatigue and what not.... I think a week is a good unit. If I see a bunch of busy weeks in a row, I should be able to tell it's time for an off week, for example.
I like the graph, too. Someone on irongarm recommended openoffice for checking out excel like power. I haven't tackled it yet. We'll see. Right now I'm still coming back from a sick induced layoff so my entries of "some pullups and pushups" wouldn't even register on the graphs, so I've got time. I'll share if I find or create anything I think is easy and useful.
