I decided to create a spreadsheet to double check some Harbin math. You can see it here:
https://docs.google.com/spreadsheets/d/1AE-arFXSLxrJsTWO4h5xqZSYed4ovbU2AP0eSb1OueM/edit?usp=sharing
Elder currently has 43 Level 1 points and 251 Level 2 points for a Harbin average of 30.3900. Elder's current L2 divisor is 98, but the final L2 divisor will be 97.
Still to go in week 9, La Salle faces Detroit Catholic Central and St. Xavier hosts Cleveland St. Ignatius. If St. Xavier wins, Elder receives an additional 6.5 L2 points. That would give Elder a Harbin average of 31.0533 going into week 10. We'll assume La Salle will lose to DCC today.
Assuming that Elder wins over La Salle next week, Elder will get 6 L1 points and 6.5 L1 points for La Salle's week 1 win over Colerain. The Panthers would then have 49 Level 1 points and 264 Level 2 points.
Assuming Cov Cath wins over Conner, Elder gets 6 L2 points.
Assuming Pick Central wins over Reynoldsburg, Elder gets 6.5 L2 points.
Assuming Springboro wins over Miamisburg, Elder gets 6.5 L2 points.
Assuming Louisville St. X wins over Pleasure Ridge Park, Elder gets 6.5 L2 points.
Assuming St. Xavier wins over Life Christian Academy, Elder gets 3.5 L2 points.
Assuming Roncalli wins over Shortridge, Elder gets 6 L2 points.
Assuming Chatard wins over Northwestern, Elder gets 5 L2 points.
That would give Elder a total of 307 Level 2 points and combined with the aforementioned 49 Level 1 points would provide a final Harbin average of 36.2402.
While week 10 has a favorable outlook for Elder's defeated opponents, it's an even sunnier forecast for Lakota West who currently have 58.5 Level 1 points, 232 Level 2 points and a final L2 divisor of 100. We can make the same assumptions for the Firebirds regarding St. Xavier (wins over St. Ignatius and LCA). Due to the nature of the GMC's scheduling, the rest of Lakota West's opponents play one another next week with Lakota East vs. Fairfield, Sycamore vs. Hamilton, Oak Hills vs. Middletown, Princeton vs. Mason, and Lakota West playing Colerain. Let's assume Fairfield, Hamilton, Oak Hills, Princeton, Fairfield and Lakota West all win. That would give Lakota West 65 Level 1 points and 294 Level 2 points for a final Harbin average of 35.9000 points.
Those two final numbers would put Elder slightly ahead of Lakota West for the #2 seed in Region 4. However, if any of Elder's opponents lose in week 10--or if Chuck Kyle wins his final Jesuit Bowl, that would be enough for Lakota West to take the second spot.
If La Salle wins today against Detroit Detroit Catholic Central, that would give Elder a little wiggle room for the second seed meaning that one--but only one--opponent could lose in week 10.
That's what I got. Let me know if my math is off.
