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)
SL Benfica's Samuel Dahl at 23 years old has the highest Pre-Peak Value Efficiency at 9.00×. That means Samuel Dahl is valued 9.00× higher than the median player in the 21-23 age bracket—representing exceptional value before reaching peak age.
In second is SL Benfica's Rafa Obrador, who is 22 years old, with a 2.00× PPVE. Third is Pedro Bondo of FC Famalicão, who is 21 years old with a 1.00× 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 9.00× means the player is worth 800% more than typical players their age—making them high-value targets before they reach peak value.

Risk-Adjusted Upside (RAU)
Upside potential weighted against forecast uncertainty. Higher RAU = better risk-reward profile.
Understanding Risk-Adjusted Upside (RAU)

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: young 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)
FC Alverca's Chissumba in the U21 age bracket has the highest Age-Share Concentration at +12.7%. That means Chissumba captures 27.0% of total market value while representing only 14.3% of players in their age group—showing dominant elite status.

How ASC is calculated: ASC = (% of total value) - (% of total players) in age bracket. A +12.7% ASC means the player captures 12.7% more market value than their numerical representation—indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
