KNLTB Tools

Adds interactive elements to various KNLTB pages to allow for faster and more realistic rating calculations and visualizations.

KNLTB Tools adds interactive panels and shortcuts to the KNLTB member portal (mijnknltb.toernooi.nl) to help you analyse ratings, simulate match outcomes, and navigate the site more efficiently. Draw & group pages — match rating simulator A floating panel loads automatically on any draw or group page. Import matches with one click, see each player's current rating, and simulate outcomes by selecting a winner. Each player's rating updates in real time based on the KNLTB DSS logistic model. A summary table shows the cumulative rating change across all entered results. You can also add matches manually or override a player's starting rating. All pages — player rating tooltips Hover any player name link anywhere on the site to instantly see their singles, doubles, and padel ratings. Ratings are fetched once and cached for the rest of your session. Home page — navigation shortcuts "Go to overview" buttons appear next to each scheduled category and the next-match banner, jumping directly to that draw. A "Rating" shortcut is added to your player profile. Player profile — charts, history & season stats An interactive rating history chart shows your singles, doubles, and padel ratings over time, with optional trend lines. A sortable match history table lets you find your best and worst results by impact. A season stats panel displays 11 performance metrics as donut charts — win rate, set conversion, comeback rate, performance vs higher/lower rated opponents, and more. All data stays on your device. No data is collected or transmitted.
