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)
Feyenoord Rotterdam's Jordan Bos at 23 years old has the highest Pre-Peak Value Efficiency at 7.14×. That means Jordan Bos is valued 7.14× higher than the median player in the 21-23 age bracket-representing exceptional value before reaching peak age.
In second is Go Ahead Eagles's Aske Adelgaard, who is 22 years old, with a 1.00× PPVE. Third is Mats Rots of FC Twente Enschede, who is 20 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 7.14× means the player is worth 614% more than typical players their age-making them high-value targets before they reach peak value.
PPVE by Age Bracket
| Rank | Player | Age | Bracket | Current Value | Bracket Median | PPVE |
|---|---|---|---|---|---|---|
| #1 | Jordan Bos Feyenoord Rotterdam | 23 | 21-23 | €5.0M | €700K | 7.14× |
| #2 | Aske Adelgaard Go Ahead Eagles | 22 | 21-23 | €700K | €700K | 1.00× |

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)
Ajax Amsterdam's Lucas Jetten at 19 years old has the highest Return-to-Peak Potential at +44%. That means Lucas Jetten is projected to appreciate 44% as they reach their peak age in 7 years-representing significant upside before entering their prime.
In second is FC Twente Enschede's Mats Rots, who is 20 years old, with a +40% RPP (6 years to peak). Third is Nazjir Held of FC Utrecht, who is 21 years old with a +35% RPP (5 years to peak).
How RPP is calculated: RPP compares a player's current market value to their forecasted peak value, calculating the percentage appreciation potential. A 44% RPP means the player is expected to gain 44% value as they enter their prime-making them excellent growth investments.
Recovery Potential by Player
| Rank | Player | Age | Years to Peak | Current | Peak Forecast | RPP % |
|---|---|---|---|---|---|---|
| #1 | Lucas Jetten Ajax Amsterdam | 19 | 7 | €700K | €1.3M | +44% |
| #2 | Mats Rots FC Twente Enschede | 20 | 6 | €5.0M | €8.3M | +40% |
| #3 | Nazjir Held FC Utrecht | 21 | 5 | €400K | €618K | +35% |
| #4 | Aske Adelgaard Go Ahead Eagles | 22 | 4 | €700K | €1.0M | +30% |
| #5 | Wouter Prins FC Groningen | 22 | 4 | €600K | €862K | +30% |
| #6 | Jordan Bos Feyenoord Rotterdam | 23 | 3 | €5.0M | €6.7M | +25% |
Risk-Adjusted Upside (RAU)
Upside potential weighted against forecast uncertainty. Higher RAU = better risk-reward profile.
Understanding Risk-Adjusted Upside (RAU)
Ajax Amsterdam's Lucas Jetten has the highest Risk-Adjusted Upside at 82.7. That means Lucas Jetten has 23% upside potential with only 0% forecast uncertainty-representing excellent risk-reward for value appreciation.
In second is FC Twente Enschede's Mats Rots with a 69.6 RAU (19% upside, 0% uncertainty). Third is Nazjir Held of FC Utrecht with a 55.6 RAU (15% 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.
Risk-Adjusted Upside by Player
| Rank | Player | Expected | Range | Upside % | RAU |
|---|---|---|---|---|---|
| #1 | Lucas Jetten Ajax Amsterdam | €864K | €765K-964K | +23% | 82.7 |

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 Twente Enschede's Mats Rots in the U21 age bracket has the highest Age-Share Concentration at +12.6%. That means Mats Rots captures 46.0% of total market value while representing only 33.3% of players in their age group-showing dominant elite status.
In second is Ajax Amsterdam's Lucas Jetten with a +12.6% ASC (46.0% value share vs 33.3% player share in U21 bracket). Third is Aske Adelgaard of Go Ahead Eagles with a +-12.6% ASC (54.0% value vs 66.7% players in 21-23 bracket).
How ASC is calculated: ASC = (% of total value) - (% of total players) in age bracket. A +12.6% ASC means the player captures 12.6% more market value than their numerical representation-indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
