This almost doesn't seem right but here it goes. Woke up this morning 5:00 am it's 60 degrees inside 12 outside. Left for work around 7 and set the thermostat at 50. When I got home at 5:30 it was 56 inside and 24 outside. It was a very sunny day today but I thought that was pretty awesome to only lose 4 degrees over a ten and a half hour period. It makes me want to finish my upgrades and see how much better I can do.
