We are #119 with schedule strength of 123. Wake and State are 73 & 79 respectively with schedule strengths of 231 & 215. I’ll never understand this formula…
I don’t really understand either. I stopped trying to figure it out. I think there is a glitch in the formulas that hurt Charlotte every year.
I wonder what our RPI would be right now if we had won against Monmouth and Hofstra. 75 to 90 maybe???

Kenpom.com: RPI Help
We are #119 with schedule strength of 123. Wake and State are 73 & 79 respectively with schedule strengths of 231 & 215. I'll never understand this formula...
The formula is not as complicated as it sounds, it’s just lengthy. I replicated the formulas in a spreadsheet (for Charlotte only) and update it each day. On any given day, I’m within 0.0001 of what’s posted on realtimerpi.com. This is the basic RPI formula.
-
25% is for Charlotte’s ADJUSTED winning percentage (home wins are only worth 0.6 wins, home losses are worth 1.4 losses; away wins are worth 1.4 wins, away losses are worth only 0.6 losses)
-
50% is for Charlotte’s AVERAGE opponents winning percentage (wins and losses are worth 1 for the opponent). When you figure the opponent’s winning percentage, you do not include any games with Charlotte. You get each opponent’s winning percentage and average them together. (It is not the aggregate wins/losses.)
-
25% is for Charlotte’s AVERAGE opponent’s opponent’s winning percentage (wins and losses are worth 1 for the opponent’s opponent). When you figure the opponent’s opponent’s winning percentage, you do not include any games between the opponent and the opponent’s opponent (games against Charlotte are not included either). Again, you would average the opponent’s opponents winning percentages.
Parts 2 & 3 become tricky when you get into conference play, because alot of teams play their opponent’s twice. When figuring parts 2 & 3, if two teams play each other more than once, NONE of the games count in figuring those winning percentages, regardless of the outcomes of the games. Also, all games with a non-Division I opponent are not included. A team is considered non-DI if that team plays more than 4 teams who are not DI.
Strength of Schedule only takes into consideration 2 & 3. After you’ve calculated the average winning percentages of 2 & 3, the formula is this:
2/3 * winning percentage from #2
1/3 * winning percentage from #3
I hope this helps.

Two words… Hofstra Monmouth. If we win those two games we’re probably in the same range as Wake and State. Sure neither of them have played anyone but neither of them have lost to a sub 200 team either.
The key to it is the fact that there is only 1 road win.

Care to run it again with wins versus Hofstra and Monmouth?

I just did a quick “what if” we had won the Hofstra and Monmouth games. If we had won those, our RPI would be in the 52-55 range.

52-55 range for RPI – SOS wouldn’t go up tremendously (RPI of .5772 and SOS of .5195)
Wow :ohmy: coulda shoulda woulda.

What a shock…

How could Strength of Schedule improve w/that scenario - if our opponents lost two more games?
FWIW - I knew the RPI would improve after Clemson - but was surprised by how much. We were around #180 (at 8-5!)because our opponents had really sucky W-L records. But that’s been getting better lately and adding in Clemson’s record bumped our combined opponents’ record above 0.500. So we jumped a lot.
Our opponents in the A10 are much improved which will keep our SOS up. Hopefully Davidson, Southern Illinois, etc. will help by beating up their conference opponents, too.

Here is the conference listing from Ken Pom’s site as of 1/10/08:
Dayton (13-1), 6
Xavier (13-3),9
Rhode Island (14-2), 17
Massachusetts (11-4), 24
Saint Joseph’s (8-4), 36
Duquesne (11-3), 41
Temple (6-7), 71
Charlotte (9-5), 116
St. Louis (8-5), 119
Richmond (8-6), 151
Fordham (5-7), 185
George Washington (4-6), 227
St. Bonaventure (6-9), 245
That’s an average RPI of 89. The average of the conference games we play is 103.
La Salle (3-9), 269

This is how SOS improved. Even though the games against Monmouth and Hofstra do not count in our opponent’s winning percentages (games against teams in question never do), all of their other games do count. Conversely, if we had won, the losses against for those teams don’t count either. So, that portion of the SOS would not change.
But, with regards to the opponent’s opponent’s winning percentage… if we had won those 2 games, our record would be 11-3 vs. 9-5. We are part of our opponent’s opponent’s winning percentage (all of our other games count in this, just not the games against those respective teams). With that said, all of our opponent’s opponent’s winning percentages would go up.
If you want the spreadsheet to play with it, let me know.

The “glitch” was that we habitually lost games that we shouldn’t early in each season. Appalachain, North Texas, Colorado, Boston U, … Our saving grace was that we generally played Cincy, UL, & Marquette twice a season and their RPIs were usually 30 or better.

cptn319, you should make this a Google Spreadsheet and open it up to the public for viewing, then just post a link in your sig or something…

Here’s my method (I don’t factor in home/road):
Today’s simple RPI
Record: (9-5) 0.643 [x25%]
Opponent’s Record (87-85) 0.506 [x50%]
Opponent’s Opponent’s Record ~0.500 [x25%]
= 0.5386
Simple RPI assuming wins over Hofstra & Monmouth
Record: (11-3) 0.786 [x25%]
Opponent’s Record (85-87) 0.494 [x50%]
Opponent’s Opponent’s Record ~0.500 [x25%]
= 0.5685
Improve +0.299
It would have bumped us from #116 to #72.

:lmao::weep:
the formula hasn’t changed since the days when we were ALWAYS in the top 40

Yea, that “glitch” is losing. Wish someone would fix that “glitch”! :lmao:
