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)
Portland Timbers's Juan Mosquera at 23 years old has the highest Pre-Peak Value Efficiency at 4.29×. That means Juan Mosquera is valued 4.29× higher than the median player in the 21-23 age bracket-representing exceptional value before reaching peak age.
In second is New England Revolution's Ilay Feingold, who is 21 years old, with a 4.29× PPVE. Third is Édier Ocampo of Vancouver Whitecaps FC, who is 22 years old with a 4.29× 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 4.29× means the player is worth 329% 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.
Understanding Return-to-Peak Potential (RPP)
Los Angeles Galaxy's Harbor Miller at 18 years old has the highest Return-to-Peak Potential at +44%. That means Harbor Miller is projected to appreciate 44% as they reach their peak age in 8 years-representing significant upside before entering their prime.

Risk-Adjusted Upside (RAU)
Upside potential weighted against forecast uncertainty. Higher RAU = better risk-reward profile.
Understanding Risk-Adjusted Upside (RAU)
Los Angeles Galaxy's Harbor Miller has the highest Risk-Adjusted Upside at 68.9. That means Harbor Miller has 23% upside potential with only 0% forecast uncertainty-representing excellent risk-reward for value appreciation.
In second is CF Montréal's Aleksandr Guboglo with a 58.0 RAU (19% upside, 0% uncertainty). Third is Leonardo Barroso of Chicago Fire FC with a 46.3 RAU (15% upside, 0% uncertainty).
How RAU is calculated: RAU divides upside potential by forecast uncertainty (RAU = Upside % ÷ Uncertainty %). A RAU of 68.9 means the upside is 68.9× 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 right-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)
Vancouver Whitecaps FC's Giuseppe Bovalina in the 21-23 age bracket has the highest Age-Share Concentration at +11.0%. That means Juan Mosquera captures 85.0% of total market value while representing only 73.9% 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 +11.0% ASC means the player captures 11.0% more market value than their numerical representation-indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
