Definitely interested in seeing moving averages as these help give some perspective on getting better or doing more fitness. I've used moving averages before on weight (http://www.fourmilab.ch/hackdiet/www/hackdiet.html) and definitely found them useful.
Site seems to be down for now - though from memory what i'd like the graph to do is be able to compare data this week to last week / this month to last month...basically anything that lets me feel like i'm doing better than before.
