Proper Single Elimination match length configuration and colour-coded Chalker leg averages.

NewTon DC Tournament Manager v4.2.4 — March 10, 2026

Overview

NewTon DC Tournament Manager Version 4.2.4 delivers two focused improvements: proper match length configuration for Single Elimination tournaments, and colour-coded leg averages in the Chalker Scoring App's Live Stats view.

This release contains no breaking changes and is a drop-in replacement for v4.2.3.

Global Config — Match Configuration

The Problem

Single Elimination tournaments previously had no dedicated match length settings. SE matches borrowed values from Double Elimination fields (Bronze and Final shared the Frontside Semifinal setting), and the Global Config UI showed only DE-specific labels — "Backside Semifinal", "Grand Final" — which are meaningless in an SE context.

The Solution

The Match Configuration section is now split into two clearly labelled sub-sections: Single Elimination and Double Elimination.

Single Elimination Fields (new)

Round	Default
Regular Rounds	Best of 3
Quarterfinal	Best of 3
Semifinal	Best of 3
Bronze Match	Best of 5
Final	Best of 5

Each field is independently configurable. If a bracket size doesn't include a particular round type (e.g. a 4-player bracket has no Quarterfinals), the setting is simply unused — no gating logic required.

Double Elimination Fields (unchanged)

All five existing DE fields (Regular Rounds, Backside Semifinal, Frontside Semifinal, Backside Final, Grand Final) are preserved exactly as before.

Layout

Single Elimination section appears above Double Elimination in both the config form and the config summary panel
Section headings use bold uppercase text with a bottom border rule for clear visual separation
Summary panel (tournament overview) updated to show both SE and DE settings

Technical Notes

Two new helper functions added to clean-match-progression.js: isSESemifinal() and isSEQuarterfinal(), which identify SE match types by round position
SE leg assignment priority order: Final → Bronze → Semifinal → Quarterfinal → Regular Rounds
Existing saved configs without SE values fall back gracefully to defaults via || n guards

Chalker Scoring App — Leg Average Colour Coding

The Feature

In the Leg Avgs row of the Match Statistics table, averages for legs the player started (threw first) are now displayed in green. Averages for legs the player did not start remain unchanged.

The green colour uses var(--accent-success) — the same CSS variable already used for the leg-starter header indicator and scoresheet winner labels, ensuring visual consistency.

Why It Matters

In darts, the player who starts a leg has a statistical advantage. Colour coding makes it immediately visible whether a strong or weak average came from a leg with or without that advantage — a useful coaching and analysis tool.

Backwards Compatibility

Older match records without firstLegStarter stored display all leg averages in plain text, unchanged.

Migration from v4.2.3

Automatic

Fully compatible with all existing tournaments
No data migration required
Existing SE tournaments will use the new default SE match lengths on next bracket generation

Config Notes

Users with previously saved configs will not have SE leg values in localStorage — the app falls back to defaults transparently
To persist SE settings, open Global Config → Match Configuration → adjust as desired → Save Match Configuration
