I guess I misread your question...preseason is a scaled down version of the algorithm...SOS, returners, tradition and state to name a few...sorry

Do you ever adjust your state scales' during the season when/if it becomes apparent a states teams seem to be undervalued or overvalued based on how well they are doing OOS?

Basically, sometimes a state will outplay its preset scale, made apparent by teams' on field results ... Do you ever change state scales midseason?

Not a bad question but you kinda late to the party

You are very late. 

I'll say he said definitively... NO TINKERING during the season to a similar question though.

Well, it's the algorithm and not me. But, I think they played SJR pretty tough and I respect Coach Augie. The on-the-field will tell. NJ is a VERY strong state. Don't think I'll get argument on that haha

NJ is not a strong STATE. There are a few good teams in New Jersey... That doesnt make the state strong... It has no depth at all.

Same can be said about Hawaii, Arizona, Maryland, and a few other states

 

All of them lack depth despite having quite a few solid teams at the top

Following up on the last part of your answer:

Do you get a chance to watch games live? If so, how do you treat the rankings when what you see is not corresponding to the proprietary rankings?

Crap... 

He did say that he has found reasons to tinker in between seasons and adjust numbers like what you are asking about though. Just never during the season. I guess I can agree with that approach to some extent. It almost seems kind of silly to leave it running if there is an obvious misjudgment of scaling like that, but, it can't be an algorithm if it's being tinkered with after the initial populating of data has been set.

Preseason ranking are usually pretty bad ... No matter who makes it.

Preseason State Scaling is also just that... Preseason. You cant know exactly where a state stands in the preseason because you dont know exactly where its teams stand.

OOS games begin to scale states automatically to an extent. If Team A from Arizona beats Team B from Colorado... Arizona gains points while Colorado loses some (as long as the 2 team ratings' allow for it)... And that begins the state scaling process. Problem is thats not enough. 

IMO, there needs to be some tinkering during the season if it becomes obvious it needs it. Use OOS game results as a guide. Scales should be messed with until game results/scores match team ratings.

 

Anyway.... Just putting my opinion out there, tinkering with state scales midseason makes more sense.

Yeah I didnt do much reading , as I knew I was late since there was already 4 pages.

I hear you. I was just trying to give you the hard evidence that he seems to have answered your question in the negative, to save you the trouble of having to go back to find it yourself, assuming (perhaps wrongly) that you wouldn't want to go back to find it.

I don't see (and I don't think anyone else can see, because it's a false presumption) that you can accurately rank teams after week 0 without already having ranked them, however inchoate those rankings may be, in week 0.

And given that fact, I think that Jeff's reasoning is correct: don't tinker, but let the chips fall where they may. If the end result is shit, then tinker in the offseason.

The end-of-the-year results are good evidence for the strength of the algorithm. If you tinker along the way, then you diminish the value of that evidence.

Both of you make a pretty good argument.

 

I think I was initially with Belly Bob on that you have to let it run once you initially populate it with all the pertinent data. 

 

I do wonder, if, say in a case where some of the pertinent data was either entered incorrectly via typo or misinformation, if they would attempt to correct it. I suppose if they did, then it would change everything before it and after it in the algorithm. If they didn't, and it was a glaring error, then it diminishes the final product as well. Kind of a damned if you do and damned if you don't type situation I think.

That's a good point, but it seems different from the one ECHS and I disagree on.

It's one thing to test your algorithm (as you intended it to work) against real outcomes on the field. It's quite another to enter data points incorrectly (so that your algorithm does't work as you intended it to work).

Well, it's sort of the same argument. If you realize after the fact that you grossly underscaled North Carolina for instance, then suddenly all the connecting data is corrupted as well. 

 

In the end of ends, not tinkering and just accepting what you got with it, as it was, is probably the right move. Once you break into tinkering, or replacing data midstream, your product is wasted. You can't say it's an algorithm after that. It would have to be called a hybrid or something else.

Why are you putting so much weight on OOS results?

As you yourself seem to suggest, the outcome of one game between two similarly ranked (or rated) teams from different states wouldn't tell us much about the quality of play in the states from which those teams come. 

As you yourself often go on and on and on about, the outcome of a game is often determined by the styles of play of the teams involved or by a few lucky plays or bad calls, which has nothing at all to do with how good the state are from which the teams come.

So why give Arizona points (and take away points from Colorado) because team A happened to beat team B on a given Friday night (or Saturday afternoon)?

Well he did say last year he had a 62% success in teams starting in the preseason 100 to those who finished the season there.He also said he only does preseason for the fans

I don't know what he meant by that.

If SOS is crucial for ranking teams in week 2, then it must also be in week 1. And if it's crucial in week 1, then must also be in week 0.

He might release preseason rankings for the fans, but he has to have them in mind himself, if he's going rank teams on the basis of SOS after the first games of the season have been played.

I misunderstood you then.

I thought you had something like this in mind: "Hmmm...This is an unexpected result. Oh, I see why. I didn't hit the keys I meant to when I was putting North Carolina's values in".

That's very different from: "Hmmm...This is an unexpected result. Oh, I see why. North Carolina is performing much better than I expected, given my algorithm for determining week 0 rankings."
