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)
Sporting CP's Ousmane Diomande at 22 years old has the highest Pre-Peak Value Efficiency at 56.25×. That means Ousmane Diomande is valued 56.25× higher than the median player in the 21-23 age bracket-representing exceptional value before reaching peak age.
In second is Sporting CP's Zeno Debast, who is 22 years old, with a 37.50× PPVE. Third is António Silva of SL Benfica, who is 22 years old with a 37.50× 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 56.25× means the player is worth 5525% 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)
SL Benfica's João Fonseca has the highest Risk-Adjusted Upside at 82.7. That means João Fonseca has 23% upside potential with only 0% forecast uncertainty-representing excellent risk-reward for value appreciation.
In second is SL Benfica's Gonçalo Oliveira with a 69.6 RAU (19% upside, 0% uncertainty). Third is Otávio of CF Estrela Amadora with a 69.6 RAU (19% upside, 0% uncertainty).
How RAU is calculated: RAU divides upside potential by forecast uncertainty (RAU = Upside % ÷ Uncertainty %). A RAU of 82.7 means the upside is 82.7× 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: young centre-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)
Boavista FC's Pedro Gomes in the 21-23 age bracket has the highest Age-Share Concentration at +7.1%. That means Ousmane Diomande captures 95.3% of total market value while representing only 88.2% of players in their age group-showing dominant elite status.
In second is CD Nacional's Chico Gonçalves with a +7.1% ASC (95.3% value share vs 88.2% player share in 21-23 bracket). Third is David Moreira of Sporting CP with a +7.1% ASC (95.3% value vs 88.2% players in 21-23 bracket).
How ASC is calculated: ASC = (% of total value) - (% of total players) in age bracket. A +7.1% ASC means the player captures 7.1% more market value than their numerical representation-indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
Value Concentration by Player

How are Liga Portugal Young Centre-Backs ranked?
Liga Portugal Young Centre-Backs are ranked by our proprietary Analytical Strength Index, which is specifically calibrated for Young Centre-Backs. The score combines six factors: Historical Achievement Index (35%) measuring peak career value, Current Performance Proxy (30%) reflecting recent market signals, Playing Time Utilization (18%) tracking minutes played, Age-Adjusted Performance Curve (12%) using position-specific peak ages, League Quality Coefficient (3%) for Liga Portugal competition level, and Club Tier Multiplier (2%) accounting for club prestige. This methodology is grounded in academic research including work by Dendir (2016) on age-performance curves and Franck & Nüesch (2012) on hedonic pricing models.
