The margin of victory piece is what's changing the math for us, and kenpom and sagarin don't take that into account. NET factors in margin of victory up to 10 points... so a 10 point victory weighs a little more than an an 8, an 8 more than a 4, etc... but a 25 pt loss doesn't weigh more than a 10 pt loss.
We have 5 wins of 10+ points, over teams ranked 41, 154, 218, 233, 334. That's zero 10+ point victories over top 150 teams before last night (and only 1 over a Top 200 team), and the Iowa win moved us up 10 places in the NET rankings on its own.
We have 8 losses of 10+ points, against teams ranked 8, 8, 11, 27, 43, 56, and 58. We also have an 8 point loss to 241 Fordham, which is nearly as bad a loss margin as they take into account, over a really poorly ranked team.
Our average conference win has been by 6 points, and our average loss has been by 12.
