F1 Pitwall — Model & Methodology

2025 Season Backtest

How the model would have performed picking teams for every 2025 race using only practice data available before qualifying.

Calibration Curve

Average actual fantasy points earned per predicted finishing position, learned from 2025 data.

How It Works

01

Practice Analysis

All three practice sessions are ingested in real time. Single-lap pace, long-run degradation, and tire compound are all captured and normalized to produce a true picture of each driver's weekend form.

02

Predictive Model

Session data is weighted and combined using parameters optimized across the full 2025 season. The model accounts for tire compounds, sprint weekend formats, and driver-specific tendencies that practice alone doesn't reveal.

03

Race Simulation

Thousands of race scenarios are simulated with qualifying variance, safety cars, pit strategies, overtakes, and DNFs. The result is a full probability distribution of fantasy points, not just a single guess.

04

Team Optimization

Every valid combination of 5 drivers and 2 constructors is evaluated against the $100M budget. Multiple strategies (balanced, safe, aggressive, value) are scored to match your risk preference.

Model Changelog

v4.2 2026-03-10
  • Environmental session weighting -- Temperature delta, night race, and calendar density modifiers adjust session weights per-circuit
  • Split weight optimization -- Separate B2B and standalone weekend weights (0.45 divergence, +0.13 error improvement)
  • Travel stress modeling -- Timezone disruption inflates Monte Carlo variance and DNF rates
  • 2026 learning loop -- Completed races feed back with 2x weight; shrinkage k decays as data grows
  • Backtest improvement -- 80.6% capture rate (up from 74.5%), 4,429 pts across 23 races
v4.1 2026-03-10
  • Post-qualifying model -- 60/40 quali/practice blend; post-quali earned 4,482 pts vs practice-only 4,429 pts (+53)
  • Qualifying calibration -- Separate quali-position-to-points lookup table learned from 2025
  • Per-driver DNF rates -- Historical 2025 rates replace flat 5% assumption in Monte Carlo
  • PU component tracking -- Grid penalty risk assessment from power unit usage data
  • Empirical pit stop model -- Team-specific pit stop point estimates from historical distributions
  • Circuit adjustments -- Overtake rates, safety car probability, and DRS zones active in estimates
  • Chip usage tracking -- SQLite-backed tracking of which chips remain available
v3.0 2026-03-07
  • Monte Carlo race simulation -- Full probability distributions instead of single-point estimates
  • Tire degradation modeling -- Per-driver deg curves from practice stint data
  • Multi-mode optimizer -- Balanced, Safe, Aggressive, and Value strategies
  • Weather integration -- Race-day forecast with confidence adjustment
  • Track-specific modeling -- Circuit characteristics feed the simulation
  • Uncertainty bands -- Point ranges, podium probabilities, and risk categories
v2.0 2026-03-07
  • Sprint weekend support -- All 23 races covered including 6 sprint events
  • Compound normalization -- Tire-adjusted lap times from calibrated 2025 data
  • Qualifying prediction -- Per-driver qualifying tendencies improve constructor scoring
  • Transfer-aware backtest -- Realistic season management with carry-forward logic
v1.0 2026-03-07
  • Initial release trained on full 2025 season
  • Empirical calibration with driver bias correction
  • Budget-constrained team optimizer

Known Limitations

  • Weather divergence between practice and race reduces prediction confidence
  • On-track incidents and safety cars are inherently unpredictable
  • Sprint weekends have less practice data available, so confidence is lower
  • Drivers who changed teams for 2026 may behave differently than historical data suggests
  • The model improves as the 2026 season progresses and more real data is available
