The fee and the prizeSame arithmetic as
Player ROI. Take every lineup built a
certain way. Add up the fees they paid and the prizes they won (ties split, DraftKings’ rule).
ROI = (won − paid) ÷ paid.
One winning ticket is a million dollars, and whatever build it sat in looks like genius: flip to
without 1st place to see what a build did for everyone else.
Blank entries paid a fee and count in the field; no build gets them.
Paid up, middle, cheapPrices move every week, so the lines do too. At each position the field is cut in
thirds by what it actually spent in that tournament that week. Quarterback and defense: the price of the slot. Running back
and receiver: the average price per player, so a third back in the flex doesn’t pass for spending more on backs.
Tight end: the priciest one in the lineup. Prices land on round numbers, so the thirds are never exactly thirds.
Season to dateFees and winnings sum across weeks, then ROI is recomputed on the totals. Share of field, cashed
and top 1% are the average of the weekly numbers, so a week with a field five times bigger doesn’t drown the others.
It is early. One slate’s hot players decide one slate’s best build; this gets more honest every week it runs.
Rake outRake out = DraftKings’ cut put back in the pool. The field returns 0%, and every number is the
decision alone. A what-if, not a ledger entry: the page opens with the rake in, the front page scores on the raked number,
and the switch is the same one as Player ROI. Each week gives back its own cut before the weeks are added up.
