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)
Académico Viseu FC's Gu Costa at 20 years old has the highest Pre-Peak Value Efficiency at 1.00×. That means Thauan Lara is valued 1.00× higher than the median player in the 21-23 age bracket-representing exceptional value before reaching peak age.

|---|---|---|---|---|---|---|
| #1 | Gu Costa Académico Viseu FC | 20 | U21 | €400K | €400K | 1.00× |
| #2 | Thauan Lara Portimonense SAD | 22 | 21-23 | €400K | €400K | 1.00× |

Recovery potential from current value to forecasted peak. Shows how much upside remains for players approaching their prime.
Understanding Return-to-Peak Potential (RPP)
Académico Viseu FC's Gu Costa at 20 years old has the highest Return-to-Peak Potential at +35%. That means Gu Costa is projected to appreciate 35% as they reach their peak age in 6 years-representing significant upside before entering their prime.

How RPP is calculated: RPP compares a player's current market value to their forecasted peak value, calculating the percentage appreciation potential. A 35% RPP means the player is expected to gain 35% 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 | Gu Costa Académico Viseu FC | 20 | 6 | €400K | €618K | +35% |
| #2 | Thauan Lara Portimonense SAD | 22 | 4 | €400K | €535K | +25% |

Upside potential weighted against forecast uncertainty. Higher RAU = better risk-reward profile.
Understanding Risk-Adjusted Upside (RAU)
Académico Viseu FC's Gu Costa has the highest Risk-Adjusted Upside at 46.3. That means Gu Costa has 15% upside potential with only 0% forecast uncertainty-representing excellent risk-reward for value appreciation.
In second is SC União Torreense's Afonso Peixoto with a 27.5 RAU (7% upside, 0% uncertainty). Third is Thauan Lara of Portimonense SAD with a 23.0 RAU (6% upside, 0% uncertainty).
How RAU is calculated: RAU divides upside potential by forecast uncertainty (RAU = Upside % ÷ Uncertainty %). A RAU of 46.3 means the upside is 46.3× 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 |
|---|---|---|---|---|---|

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 weak depth (avg Z-score: -0.00). RPI: -0.00.
