How Kelly scores fantasy leagues

Kelly reads each synced league's scoring settings from its platform: points per reception, passing and rushing yards, bonuses, kicker distance tiers, team defense and every custom rule. A change to the rules mid-season applies from the week it was made, so each week is scored by the rules it was played under.

While games are on, Kelly scores starters from its own play-by-play feed, then from the official box score once it lands. Each starter's points say where they came from. A total scored this way is labelled "Kelly live". Where Kelly cannot place a player, it shows the platform's number and says so.

The platform's score is the official one. When a week goes final, and again each day from Tuesday to Friday as stat corrections land, Kelly rescores every team from the box score and compares it with the platform's points. A team more than 0.1 point apart is marked as different, with the cause of its largest player gap: rounding, an unmatched player, a stat correction, a platform rescore, a team defense or a rules change. Every check is kept, and your league's page says how many teams matched.
