Since the Dave House North has been charging since late in the afternoon on the 7^th, it is catching up to the Dave House South. It is hard to directly compare the time it took both buildings to charge up since the Dave House South had cloudy weather when it first started charging. However, the Dave House North caught up in 3 days and in the next set of graphs, it should over take the Dave House South. The Andy Shack has been doing misleadingly well with all of the sunny weather and warmer outside temperatures, but at the first return of cold, it will hemorrhage heat while the Dave Houses will hold onto their heat. The small spike in the Dave House graphs is from the morning sun, which is now higher in the sky as we move towards the spring equinox. I made white shades to block this effect from future graphs.
