Live Undercut/Overcut Calculator

Overview

Analyzes live Formula 1 race data to calculate the probability of a successful undercut or overcut. This pillar gives traders a crucial edge in dynamic, in-race trading markets by forecasting the outcome of key strategic decisions.

What It Does

This pillar models tire performance degradation for each driver using their most recent lap times and current tire compound. It projects future lap times on both old and new tires, factoring in the time lost in the pit lane. The model then compares the projected track position after a stop against the alternative of staying out, signaling the optimal move.

Why It Matters

Pit stops are the most significant strategic events in an F1 race and frequently decide the winner. This pillar replaces gut feeling with a data-driven forecast, identifying high-probability opportunities for position changes before they happen on screen.

How It Works

First, the system ingests live lap time data for all cars on track. Second, it calculates the rate of performance loss for each car's current tire set. Third, it simulates the outcome of pitting on the current lap, including pit lane time loss and projected pace on fresh tires. Finally, it presents a clear signal on whether an undercut or overcut is likely to succeed.

Methodology

The core calculation uses a 5-lap rolling window to establish a linear regression of lap time degradation. The undercut/overcut success probability is determined by comparing the projected race time over the next 3 laps for two scenarios: (1) pitting now, and (2) staying out. The model accounts for track-specific pit lane time loss and the expected performance delta between tire compounds.

Edge & Advantage

It provides a precise, quantitative signal on a highly dynamic race element that most viewers and commentators assess qualitatively, often giving an edge of several seconds to a full lap.

Key Indicators

• Lap Time Degradation Curve

  high

  The rate at which a driver's lap times are slowing on their current set of tires.

• Pit Window Traffic

  high

  The presence of slower cars that a driver might exit the pits behind, negating the advantage of fresh tires.

• Gap to Rival Car

  medium

  The time gap to the car ahead or behind, which determines if a pit stop can be made without losing track position.

Data Sources

• F1 Live Timing API

  Provides real-time lap-by-lap data, sector times, and driver positions during a race.

• Pirelli Motorsport Data

  Official supplier data on tire compound performance characteristics and expected lifespan.
