Return From Injury/Break Performance Dip

Overview

This pillar analyzes a player's historical performance in their first few games after returning from an injury or extended break. It provides a data-driven estimate of the 'rust' factor, helping to identify overvalued players in prediction markets.

What It Does

It establishes a player's baseline performance using key metrics from the 90 days prior to their absence. Then, it compares this baseline to their performance in the first three official matches upon their return. The analysis considers the length of the break and the nature of the absence, such as a hand injury versus a mental health break, to model the expected performance dip.

Why It Matters

The market often prices a returning star player based on their peak reputation, not their immediate form. This pillar provides a statistical edge by quantifying the likely short-term underperformance. This allows for more accurate predictions on player prop bets and match outcomes where that player is a key factor.

How It Works

First, the system detects a player returning from an absence of 14 days or more. It then calculates their average performance rating across key game-specific stats (e.g., KDA, ADR) from the 3 months before the break. This baseline is compared against their performance in the first 1 to 3 matches back to generate a 'Return Performance Score'.

Methodology

The core metric is the Performance Dip Score (PDS), calculated as: PDS = (Avg_Post_Return_Metric / Avg_Pre_Break_Metric) - 1. The pre-break metric is a 90-day rolling average. The post-return metric is a weighted average of the first 3 games. A PDS of -0.15 indicates a 15% performance drop. The model applies a heavier negative weight for hand or wrist injuries and for absences longer than 30 days.

Edge & Advantage

This pillar provides a specific, quantitative edge by forecasting the 'rust' factor that most bettors only guess at, creating opportunities to bet against inflated market expectations.
