The quickest way into the polls is to beat one of the over rated SEC teams (that's every one but Alabama).

Except if you are a Big Ten team (Wisconsin).

Wisconsin who went unranked to in the top 10 after beating LSU? That Wisconsin?

My bad, I didn't see that jump! I saw 3 in the Top 10 and my mind jumped to OSU, Michigan, and Michigan State.

This is not hard to determine, We can simply use the voter calculus: The chances of being ranked in the top 25 are:

 

(W/(1+L) + R + H + (25 - PR)/3)/ G = BRPI (Being Ranked Probability index)

 

where W= wins, L= losses, R = wins over ranked teams, H = wins over highly ranked teams, PR = previous ranking (PR of unranked teams is 0), and G = games played

 

If the BRPI is >= 1 you will be ranked.

 

This equation is guaranteed to be 100% accurate 75% of the time.

 

Please note that the equation used to be (W/(1+L) + R + H + SB+ (25 - PR)/3)/ G = BRPI where SB was 1 for any SEC team, and 0 for anyone else. The SB adjustment has been removed for this season.

 

What could be easier. We see that Nebraska's numbers are:

 

current: ((2/(1+0)) + 0 + 0 + (25-26)/3)/2 = 0.83

 

Win over the Ducks : (3/(1+0) +1 + 0 +(25-26)/3)/3 = 1.2

 

Last year's final rankings: (6/(1+7) +1 + 1 + 0 + (25-26)/3)/13 = 0.18 (note: last year's equation had the SB cofactor that is gone from this year's equation, though there is a move by ESPN to have it reinstated)

 

Note: edited for misplaced ")"
