Player percentage = (actual − line) ÷ |line| × 100. A zero line has no meaningful percentage; the actual difference is still shown.
Position group totals: sum the matched DK lines and sum the same players’ recorded actuals across selected weeks, then calculate (actual total − line total) ÷ |line total| × 100. This is not an average of player or weekly percentages. A zero combined line has no meaningful percentage; empty groups display dashes. Players without a line and comparisons with missing, pending, unknown, DNP or void results are excluded from both totals. All recorded comparisons count, including unders, pushes and unselected lines.
Gap and repeat shading: stronger shading draws attention to larger gaps and repeated results. Muted green means above the line, muted red means below, and yellow means near neutral. These are visual guides to saved results, not statistical significance or win probability. Missing or undefined percentages stay uncolored. The colors do not change your picks or the recorded evidence.
Participation: missing results, pending bets, DNPs and voids do not count as zero or as wins/losses. A real recorded zero is retained. Book settlement rules can differ.
Evidence: historical DraftKings quotes come from the local Action Network archive, joined on game, player ID and team. Ambiguous identities and review-flagged prices are excluded. Remaining identities are mechanically matched, not manually audited. Quote times and settlement are unverified; these are not certified closing lines or a tradable backtest. Multiple quotes, if present, use the latest extraction then quote ID—not the best result.
Your data: highlights, completed-matchup markers and betslip picks are saved in this browser on this site, not in the old projection tracker. Use Your data at the top of the page (on a phone, My Picks under Slip details) to back them up (with your settings and fantasy leagues) and to restore them in another browser. Prop lines always come from the published DraftKings data; they cannot be added, edited or hidden by hand.
