That was a joke, but I can calculate this much. Tonight, the expected wins for Chicago were adjusted down .6, and they went up for us by .4.
That means the site had given us a 40% chance of beating them.
Edit: On second thought, it means CoolStandings had given each team 60% chance of winning, which is impossible. Other considerations must have played a part, namely: The day's performance of remaining opponents of Portland and Chicago changed the remaining Strength of Schedule for Portland and Chicago.
