The Fan Effect Index
One question, asked of twelve Finals performances: would I look it up again? Not was it clean. Not did it earn the sheet. Would I, in February, on a phone, in a parking lot, type the name into a search bar and watch the whole thing over. That question produces a different order than the judges produced. Here is both orders, the size of the disagreement, and an honest attempt to find out what the disagreement is actually made of.
Every scoring argument in this activity eventually collapses into the same two camps. One side says the sheet is the truth and everything else is sentiment. The other side says the sheet misses the thing that made you drive four hours. Both camps have been shouting past each other for as long as there have been recaps.
They are both right. They have always been both right. They are measuring different quantities and calling them by the same word.
So this is the desk putting its own number on the record, in public, where it can be wrong. The Fan Effect Index ranks the twelve Finals performances by rewatch value and nothing else. Then it gets tested against the recap, because a metric you never check against reality is not a metric, it is a mood.
| FEI | Corps | Finals | Judges | Divergence |
|---|---|---|---|---|
| 1 | Blue Devils | 97.500 | 2 | +1 |
| 2 | Bluecoats | 99.100 | 1 | -1 |
| 3 | Carolina Crown | 97.038 | 3 | even |
| 4 | Santa Clara Vanguard | 95.025 | 5 | +1 |
| 5 | Phantom Regiment Fan Favorite | 92.600 | 7 | +2 |
| 6 | Boston Crusaders | 95.675 | 4 | -2 |
| 7 | The Cavaliers | 92.175 | 8 | +1 |
| 8 | Troopers | 86.950 | 11 | +3 |
| 9 | Spirit of Atlanta | 88.588 | 10 | +1 |
| 10 | Blue Stars | 94.137 | 6 | -4 |
| 11 | Colts | 90.125 | 9 | -2 |
| – | Blue Knights | 86.175 | 12 | unranked |
| 12 | Madison Scouts not in Finals | – | – | n/a |
Madison Scouts are on the index and not in the field. They finished 14th in DCI World Championship Semifinals at 86.250 and did not march Finals, so there is no Finals score to put beside them, no placement to disagree with, and no caption ranks within a field they were not in. They are ranked here because the rewatch question does not care who made the cut, and they are kept out of every correlation below because the arithmetic does.
Yes. You are correct. Blue Knights are missing. That is not an oversight and it is not a clerical error. Blue Knights made Finals, played the show, and finished 12th at 86.175, all of which is a genuine accomplishment that thousands of people would trade a year of their life for. The index still has nothing to say about them, because the index only answers one question and the honest answer here was no.
Start with the assumption everybody makes. If effect and craft really were pulling in opposite directions, the two books on the recap would disagree with each other. They did not. Ranking the twelve corps by the two General Effect captions alone, and then ranking them again by the six performance captions alone, produces orders that correlate at +0.986. The effect book and the craft book named nearly the same order, top to bottom.
So there is no war on the sheet. The corps the judges found most effective were, with almost no exceptions, the corps the judges also found cleanest. Whatever the index is disagreeing with, it is not one half of a divided panel.
And it does disagree. Against the judges' final order the index correlates at +0.809. Against the effect book alone, +0.791. Against the craft book alone, +0.809. Close together, all three, and all of them short of agreement. The index is not a noisier copy of the sheet and it is not the effect book in disguise. It is picking up something the recap does not have a column for.
Rank every corps within every caption, so that a number means position on the field rather than a score in a vacuum. Then measure each corps' spread: the distance from its best caption rank to its worst. A corps sitting third in all eight captions has a spread of zero and no signature. A corps sitting second in one caption and eighth in another has a spread of six, and people walk out of the stadium talking about the second one.
The corps the index ranks above their placement average a spread of 2.75. The corps it ranks below their placement average 2. Santa Clara Vanguard and The Cavaliers are jagged, at 3.5. Bluecoats, Boston Crusaders and Blue Stars are smooth, every one of them sitting at 2.
That is the whole disagreement, and it is not a disagreement about quality. The recap integrates eleven minutes and rewards the corps that was excellent in every one of them. A rewatch decision is made by the single best ninety seconds, and ninety seconds is exactly what a spread of six buys you. Both instruments are working correctly. They are pointed at different things.
| FEI | Corps | Judges | Spread | Peak caption | Rank there |
|---|---|---|---|---|---|
| 1 | Blue Devils | 2 | 2 | Brass | 1 field best |
| 2 | Bluecoats | 1 | 2 | General Effect Music | 1 field best |
| 3 | Carolina Crown | 3 | 6 | General Effect Music | 2 |
| 4 | Santa Clara Vanguard | 5 | 4 | Percussion | 2 |
| 5 | Phantom Regiment | 7 | 2 | Percussion | 6 |
| 6 | Boston Crusaders | 4 | 2 | Color Guard | 3 |
| 7 | The Cavaliers | 8 | 3 | Percussion | 5 |
| 10 | Blue Stars | 6 | 2 | General Effect Music | 5 |
The other independent check on Finals night was a kid's tier list, assembled without reference to a single caption score, purely on the basis of what the kid wanted to see again. Which is the FEI's exact method, arrived at independently, by someone who has never read a recap sheet. Methodologically this is the best validation the index received all weekend.
It put Blue Stars above Phantom Regiment.
I will fight this child. Now. They are immature and need to be corrected.
The intellectually honest version of that reaction is worth stating, because the reaction itself is the point. An independent validator using the same method reached a different answer on one placement, and the desk's instinct was not to update, it was to challenge a minor to single combat. Everyone defending a scoring opinion tonight, in every section of that stadium, is doing some version of that. The judges included. So am I.
The difference is only that the panel had to publish theirs to three decimal places and sign it. Which is a good argument for humility, and a better one for publishing your own numbers where somebody can check them.
Everything above is one person's answer to one question. That is the honest limit of it. So the same question is now on every score page, pointed the other way: for any corps on any night this season, would you look that performance up again?
One answer, yes or no, and then the part that matters more than the answer: tell me why. The why is required, and it is required for a specific reason. A bot can click a radio button all day. A bot will not write you a sentence about why a drum corps show is worth watching twice. That sentence is the whole door policy, which is why there is no puzzle to solve and no box to tick.
Bluecoats won the 2026 Drum Corps International World Championship with a 99.100, the first score of 99 anybody put on a board this season, and they earned every thousandth of it. The index has them 2nd. Both of those sentences are true and neither one is an attack on the other.
That is the entire thesis. A recap is a measurement of execution against a written standard, performed by trained people under time pressure, and it is very good at what it does. It is not a measurement of what you will still be thinking about in February. Nothing on that sheet was ever trying to be.
The judges will disagree with this index. They are wrong. They are also, at the same time and without contradiction, entirely correct about the thing they were actually asked to score.
See you in February, in a parking lot, on a phone.
