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.

Age-Share Concentration (ASC)
Identifies players capturing disproportionate value relative to age group representation. Positive ASC = value concentration.
Understanding Age-Share Concentration (ASC)
Zulte Waregem's Emran Soglo in the U21 age bracket has the highest Age-Share Concentration at +-8.8%. That means Emran Soglo captures 1.2% of total market value while representing only 10.0% 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 +-8.8% ASC means the player captures -8.8% more market value than their numerical representation-indicating marquee status. ASC > +15% = elite dominance, ASC < -15% = potential value targets.
