H2H

I'm confused with H2H. I will give you an example.

3A 126
Caleb Smith beat Josh Wilson by MD last weekend and Caleb went from #1 to #2 due to -.6 in the head to head column. I'm pretty sure prior to that match Caleb had 0.0 in the H2H column. Caleb has lost both his matches this year to Ethan Oakley in 2A, who's ranked #2. Just seems that a direct H2H would have more value and effect the rankings in a more true way.

No Dog in the fight just something I noticed.

That definitely seems like a mistake since out of classification H2H does not count (Like Oakley vs. Smith). Josh should have the - H2H points for his Caleb. Just the way I see it.

We actually do make H2H adjustments for all wrestlers in a weight class even if their schools are in a different class. Caleb Smith has a downward adjustment because of his losses to Ethan Oakley. Caleb and Josh Wilson are super close in their overall score, so they might swap again soon. Great tournament for Caleb to beat Josh and the #3 ranked wrestler in their too.

The H2H adjustments can be confusing, especially late in the season. We won't get them all right but we do get about 80% of the year-end state tournament matches correct every year, so we will stick with our algorithm even when common sense argues otherwise in specific cases. It's one of the side effects of having an objective system.

In the overall 220, Levi Andrews has -1.1 H2H. His losses are very close twice to highly ranked Tristan Norris and once to once to Nick Minacapelli (no. 1). He has beaten Dallas Rash twice and pinned Jaron Greer. Rash and Greer are both ranked higher than Levi and neither have negative H2H. It's no big deal, but that does not quite make sense.

It is because of the negative head-to-head adjustment from his loss to Norris. We start at the bottom of the rankings by total score before head to head adjustments then work our way up. Before h2h Rash is 97.4%, Andrews is 98.3% and Norris is 99.1%. Rash goes first for H2H, and he did not beat anyone above him. Then goes Andrews – again no H2H. Finally Norris. He dropped significantly due to H2H from his loss at the beginning of the season to Grayson Cannon. But then he got a positive H2H for beating Andrews. After that H2H, Rash squeezed between them in the rankings, but Andrews' turn for H2H adjustments is already over. Not ideal, but if we keep going it becomes an endless loop. Hopefully it will straighten out over the rest of the season.

Hope that helps!

H2H "punished" a wrestler with a 97.4% Top 3 score due to a DQ to a lower ranked (22.3% adj) opponent with a -4.2 H2H score. Seems like DQs shouldn't be included in the algorithm for H2H IMHO because it skews the data. Great site, thank you. Full disclosure, I have a dog in the fight.

3A - 160, McCafferty
I've been comparing my wrestler and maybe it's not the DQ that brought down his H2H but I can't figure out why such a low H2H score. Adj average of his losses is to 90% + wrestlers except the DQ.
Forgive me, I'm on a business trip and it's my day off - too much time on my hands.

H2H means that the wrestler had two matches with the same wrestler. Josh Wilson at 132 3A is 37-0 and gets a .01 addition for head to head when there wasn't one. Please enlighten me.

I hate to keep pounding this H2H argument, but with all due respect to ADM, you keep making an argument that makes no sense. Could it be that the algorithm that calculates H2H is just flawed. You will note on the list below, that Levi Andrews has -1.1 H2H. Jaron Greer has 0, Dallas Rash has 0. Now, consider this, Levi pinned Greer, and beat Rash twice this year. Levi's only losses are to Minacapelli, Norris, and Keyonte Hamilton (ranked 3rd in the nation from Georgetown Prep, Md, and I am not talking about Rankwrestlers ranking, but real national ranking). I get the H2H adjustment, but how do the kids Levi clearly beat have 0, and you justify Levi with -1.1? It is not big deal, this is just a ranking and has no effect on the state championship, but for the sake of argument, your system just simply does not make sense.
