[quote=@catchamber]Photovoltaic efficiency is constantly increasing[/quote]

If I go from spending my whole waking day sitting sedentary at my computer jerking off on RoleplayerGuild, to spending 99.9% of my day on the Guild and the other .1% lifting a ten-pound dumbbell for a minute and a half, I've "improved" my physical fitness. That doesn't mean I've improved [i]enough[/i] (quantitatively), or that I'm improving [i]quickly enough[/i] to see practical results.
