Bye Week Impact Calculator
Estimate the performance boost (in points) a team gains from a bye week rest advantage over their upcoming opponent.
Days of Rest for Bye Team
Typically 14 days for a standard bye week (range: 7–21)
Opponent's Days of Rest
Standard week = 7 days (range: 3–14)
Opponent's One-Way Travel Distance (miles)
Distance opponent must travel to the game (0–3000 miles)
Bye Team Injury Recovery Rate (%)
Percentage of injured players expected back after bye (0–100%)
Is the Bye Team Playing at Home?
Yes No

// --- Input Validation --- var errors = []; if (isNaN(daysRest) || daysRest 21) errors.push("Bye team rest must be between 7 and 21 days."); if (isNaN(oppRest) || oppRest 14) errors.push("Opponent rest must be between 3 and 14 days."); if (isNaN(travelMiles) || travelMiles 3000) errors.push("Travel distance must be between 0 and 3000 miles."); if (isNaN(injuryPct) || injuryPct 100) errors.push("Injury recovery rate must be between 0 and 100%.");

/ * Formula (all components in estimated point impact): * * 1. Rest Advantage Component: * restAdvantage = (daysRest - oppRest) * REST_FACTOR * REST_FACTOR = 0.15 pts/day (based on NFL research: ~2 pts per full bye advantage) * * 2. Travel Fatigue Component (opponent penalty): * travelPenalty = travelMiles * TRAVEL_FACTOR * TRAVEL_FACTOR = 0.001 pts/mile (cross-country ~3 pts fatigue penalty) * * 3.

#### Formula
Total Bye Week Impact (pts) = (Bye Team Rest Days − Opponent Rest Days) × 0.15 + Travel Miles × 0.001 + (Injury Recovery % / 100) × 3.0 + Home Field (2.5 if home, 0 if away)
Each component is expressed in estimated point differential added to the bye team's expected margin. The rest factor (0.15 pts/day) is derived from NFL game outcome studies showing ~2-point advantage for a full bye (14 vs 7 days). Travel fatigue (0.001 pts/mile) reflects opponent performance degradation over long distances. Injury recovery cap (3.0 pts) represents full roster restoration value.
