About The System

VollApp replaces guesswork with data. We calculate hybrid metrics to identify the true impact of players in attack, defense, and reception.

Methodology

OHBS (Hybrid Score)

Overall Hybrid Score. A weighted combination of attack efficiency, defensive volume, and error reduction. The ultimate MVP metric.

AFI (Attack Flow)

Attack Flow Index. Goes beyond kill %. It factors in "out of system" balls and clutch points to measure true offensive value.

DI (Dig Index)

Evaluates defensive positioning. A high DI means the player is digging hard-driven balls, not just free balls.

RR (Reception)

Reception Rating. The percentage of passes that allow the setter to run a full 3-option offense.

Who uses VollApp?

Currently in Beta (v2.6), VollApp is designed for scouts, agents, and performance analysts who need a deeper look than standard box scores.
