Home field advantage and home vs away match ups are two different things. Neither are accounted for in your circle jerk.
And your 7th grade algorithm is meaningless at this time of year. Maybe it might make more sense at the end of the season, but right now it’s worthless and does not “prove” shit.
For instance, the fact that The Griz must go on the road to Reno’s for Sale stadium likely to win the BSC should be weighted, and is much more important than your silly, arbitrary, capricious, assigned number guesses.
Besides, when The Griz come to town it’s like everyone’s Super Bowl.
