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)
Paris Saint-Germain's Nuno Mendes at 23 years old has the highest Pre-Peak Value Efficiency at 10.00×. That means Nuno Mendes is valued 10.00× higher than the median player in the 21-23 age bracket—representing exceptional value before reaching peak age.
In second is Paris FC's Nhoa Sangui, who is 19 years old, with a 3.13× PPVE. Third is Melvin Bard of OGC Nice, who is 24 years old with a 2.14× 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 10.00× means the player is worth 900% more than typical players their age—making them high-value targets before they reach peak value.
PPVE by Age Bracket

|---|---|---|---|---|---|---|
| #1 | Nuno Mendes Paris Saint-Germain | 23 | 21-23 | €70.0M | €7.0M | 10.00× |

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)
Paris FC's Nhoa Sangui has the highest Risk-Adjusted Upside at 96.4. That means Nhoa Sangui has 36% upside potential with only 0% forecast uncertainty—representing excellent risk-reward for value appreciation.
In second is Stade Brestois 29's Justin Bourgault with a 86.2 RAU (31% upside, 0% uncertainty). Third is Mahamadou Nagida of Stade Rennais FC with a 86.2 RAU (31% 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.
Risk-Adjusted Upside by Player

|---|---|---|---|---|---|
| #1 | Nhoa Sangui Paris FC | €3.4M | €2.9M-3.9M | +36% | 96.4 |

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 weak 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)
AJ Auxerre's Fredrik Oppegård in the 21-23 age bracket has the highest Age-Share Concentration at +20.5%. That means Nuno Mendes captures 43.3% of total market value while representing only 22.9% of players in their age group—showing dominant elite status.
In second is Stade Rennais FC's Quentin Merlin with a +20.5% ASC (43.3% value share vs 22.9% player share in 21-23 bracket). Third is Nuno Mendes of Paris Saint-Germain with a +20.5% ASC (43.3% value vs 22.9% players in 21-23 bracket).
How ASC is calculated: ASC = (% of total value) - (% of total players) in age bracket. A +20.5% ASC means the player captures 20.5% more market value than their numerical representation—indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
