This is GPP-only. The database covers harvested large-field NFL tournaments (Milly Makers and their companion contests), not anyone's full DFS record. Cash games, small-field contests and unharvested tournaments are absent. A negative number here is not evidence of a losing player.
ROI is net over fees. −40% means they lost 40 cents of every dollar staked in these contests. Rates like cash % and top-1% are per entry, so a 150-max entrant and a single-bullet entrant are directly comparable. "Profitable contests %" is per contest, and is not comparable across volume tiers.
"Duplicated" means somebody else submitted your exact lineup. It is not you entering the same lineup twice (DraftKings blocks that). In a tournament every duplicate splits the prize, so running unique is what makes a big score worth having.
Raw duplication rate is close to meaningless on its own, because it swings enormously with field size and buy-in — a $20 Milly duplicates far more than a $1,000 small-field. So we show the duplication index: your rate divided by the rate of the exact contests you played, weighted by how many entries you fired into each. Below 1.00 means you ran more unique than the rooms you sat in. Above 1.00 means you were chalkier than the field around you.
Handles can split. DraftKings account renames are invisible to the source data, so a player who changed handles appears as two separate records. There is no way to detect or merge them.
Rake is already priced in. The field as a whole runs about −12.6% by construction; that is the house edge, not skill. Judge a record against that line, not against zero.
