How Blue Stars turned 1.8 down into 1.537 up on Phantom Regiment
Blue Stars were 1.8 behind Phantom Regiment when the two first met on July 5 at River City Rhapsody, and finished 1.537 ahead of them at Finals. The piece argues the swing is a General Effect Music story: it is the caption the two end the season furthest apart in, worth 0.375 of the final margin.
This is a reading of the sheets rather than a report of an event. The rows it argues from are printed underneath it so the argument can be checked rather than taken.

How the numbers are weighted
General Effect counts twice. The two effect captions carry 40 of the 100 points and the six performance captions carry 60, so a tenth moved in effect is worth two tenths moved in percussion. Every weighted figure in this piece is scaled that way; the unweighted caption marks are printed as the recap prints them.
