Exploring HPI in the Placard League 2025/26

by Mário Cesar Navarro

I’ve added a new interactive feature to the site: a fully embedded Tableau dashboard that tracks the Handball Performance Index (HPI) throughout the Placard League 2025/26 season.

This dashboard offers a clean, data‑driven look at player impact across the competition. You can explore performance trends, compare athletes, and dive into the metrics that shape the narrative of the season — all in an intuitive, dynamic format.

What you’ll find inside:

HPI evolution across matchdays
Player comparisons by team, position, or overall impact
Visual insights into performance peaks and consistency
A data experience designed for coaches, analysts, and fans who want more than just the final score

The dashboard is now available directly on the site, always up to date as the season progresses.
If you prefer to view the original Tableau version, you can find it here:

This addition is part of an ongoing effort to bring deeper analytical tools to the Portuguese handball community and make performance data accessible to everyone who loves the game.

EHF EURO 2026: Offensive Impact Rate: Who Truly Drove Their Team’s Attack?

The Offensive Impact Rate (OIR) is a metric designed to evaluate each player’s real offensive contribution during the EHF EURO 2026. Instead of focusing only on goals or raw volume, OIR combines positive actions (goals, assists, 7-meter penalties won) and negative actions (missed shots, turnovers, technical faults), and normalizes everything by the player’s actual time on court.
