The archive is empty until the first contest standings export is dropped into the optimizer. If you played a contest, DraftKings lets you export the full standings — drop that CSV on the app and the anatomy is computed on your machine; sharing it here is one click and anonymous.
In a guaranteed-prize-pool contest you are not paid for being right; you are paid for being right alone. A lineup that 40 other entries also hold splits first place 41 ways. Projection tools sell you the highest-projected lineup; that lineup is, by construction, the most duplicated one in the field. This archive measures the thing that decides GPPs — how many people had the winner's exact nine — from the contests' own standings files, and the optimizer prices every lineup it builds against it.
