Scout Tools
Advanced analytics for scouting and recruitment decisions. Each tool provides unique insights into player value, potential, and market dynamics.
Pre-Peak Value Efficiency (PPVE)
Identifies pre-peak players offering exceptional value relative to their age bracket. Higher PPVE = better value.
Understanding Pre-Peak Value Efficiency (PPVE)
FC Utrecht's Souffian El Karouani at 24 years old has the highest Pre-Peak Value Efficiency at 13.33×. That means Souffian El Karouani is valued 13.33× higher than the median player in the 24-26 age bracket—representing exceptional value before reaching peak age.
In second is PSV Eindhoven's Anass Salah-Eddine, who is 23 years old, with a 8.00× PPVE. Third is Owen Wijndal of Ajax Amsterdam, who is 25 years old with a 5.00× PPVE.
How PPVE is calculated: PPVE compares a player's current market value to the median value of all players in their age bracket. A PPVE of 13.33× means the player is worth 1233% more than typical players their age—making them high-value targets before they reach peak value.

Return-to-Peak Potential (RPP)
Recovery potential from current value to forecasted peak. Shows how much upside remains for players approaching their prime.
No RPP data available (requires forecast values in database)
Risk-Adjusted Upside (RAU)
Upside potential weighted against forecast uncertainty. Higher RAU = better risk-reward profile.
Understanding Risk-Adjusted Upside (RAU)
Twente Enschede FC's Mats Rots has the highest Risk-Adjusted Upside at 96.4. That means Mats Rots has 36% upside potential with only 0% forecast uncertainty—representing excellent risk-reward for value appreciation.
In second is Sparta Rotterdam's Mike Kleijn with a 86.2 RAU (31% upside, 0% uncertainty). Third is Aske Adelgaard of Go Ahead Eagles with a 75.2 RAU (26% upside, 0% uncertainty).
How RAU is calculated: RAU divides upside potential by forecast uncertainty (RAU = Upside % ÷ Uncertainty %). A RAU of 96.4 means the upside is 96.4× greater than the uncertainty—making it a high-confidence growth opportunity. Target RAU ≥2.0 for balanced risk-reward.

Roster Pressure Index (RPI)
Squad depth pressure based on Z-score distribution. Negative RPI = thin depth, positive = deep roster.
What This Shows
Z-Score explained: Measures how many standard deviations a player's strength is from the position average. Z-Score = 0 means average, +1.0 is one standard deviation above average, -1.0 is below average.
How to use: RPI < -1.0 indicates critical depth shortage. These positions need immediate reinforcement. RPI > +1.0 suggests strong depth, allowing selective, high-value additions only.
Current market: left-back position shows strong depth (avg Z-score: 0.00). RPI: 0.00.

Age-Share Concentration (ASC)
Identifies players capturing disproportionate value relative to age group representation. Positive ASC = value concentration.
Understanding Age-Share Concentration (ASC)
Twente Enschede FC's Bas Kuipers in the 30+ age bracket has the highest Age-Share Concentration at +-7.6%. That means Bas Kuipers captures 2.7% of total market value while representing only 10.3% of players in their age group—showing dominant elite status.
In second is Fortuna Sittard's Daley Sinkgraven with a +-7.6% ASC (2.7% value share vs 10.3% player share in 30+ bracket). Third is Patrick van Aanholt of Sparta Rotterdam with a +-7.6% ASC (2.7% value vs 10.3% players in 30+ bracket).
How ASC is calculated: ASC = (% of total value) - (% of total players) in age bracket. A +-7.6% ASC means the player captures -7.6% more market value than their numerical representation—indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
