My team is in D3 in a conference with pretty much D and D+ HCAs. My average home-away point swing against my divisional opponents was 21 points, all games after the 16th. If you take out the bottom feeding sim team that I actually beat by more on the road, my average point swing against the 4 other human-coached teams was 29.25 points per game. That is ridiculous. In the past HCA in D3 was virtually worthless. I understand that this is not accurate - in reality even D3 schools perform at least a bit better at home, and some HCA is necessary to make the RPI calculation meaningful. This definitely seems like too much, though.
