Derby & District Chess Club — League Tracker

This page is at an experimental stage — please double-check anything that looks wrong. Data updates overnight, so today's results won't appear until tomorrow.

Sourced from the public ECF LMS results system and the ECF ratings API. Team rosters and grades are straight data; the eligibility grid below is a computed aid, not a ruling — see its own note.

Derbyshire Club Team Squads

Every team across all 4 Derbyshire & District divisions this season (30 teams, every club) — not just Derby's own. Each division page lists every team's players who've appeared in a completed fixture, broken down by board.

Eligibility (A–F)

Eligible / Not eligible / Named — a simplified 3-state view. Computed from Rule 8/9/10/11(b)/11(c) as currently written (DCA rulebook). "Named" only applies to the Division 1 team a player is formally locked to (an 11(b) declaration, or having exhausted their play-up allowance for that team) — lower-division teams (C–F) never show "Named", since 11(b) doesn't apply there. This is a computed aid to double-check against the rulebook and the club's own records, not a ruling — especially while the 4 named Division 1 players haven't been declared yet.

Remember Rule 11(c): a player cannot play for a team in its last 3 fixtures of the season if they haven't already played for the club (any Derby team) that season. Captains can seek an exemption from the controller before the match.

Team rosters & performance

Grade = current ECF standard grade. Performance = an estimated performance rating for games played for that team this season (average recorded opponent grade + 400 × score differential ÷ games) — this is a simple approximation, not confirmed to match the ECF/DCA's own official calculation. Treat as indicative, not authoritative — see the note under "Overall performance" below for the full flag. Shows only players who've actually played for that team.

No appearances recorded yet this season.

Overall performance (all teams combined)

Every non-X squad member (plus anyone else who's actually appeared this season), aggregated across every Derby team they've played for. Zero-appearance players show P0 with "n/a" score/performance — expected this early in the season, not an error.

Performance rating — formula not confirmed against DCA/ECF's own method. The figure shown is a common simplified approximation (average recorded opponent grade + 400 × score differential ÷ games played). The club's own season-report documents describe performance ratings as "recorded by the league" (i.e. computed by the ECF LMS itself), which likely uses a table-based method rather than a flat 400-points-per-game rule, and may treat unrated opponents or draws differently. This wasn't confirmed before filing this round — treat every Performance figure on this page as an indicative same-season sanity check, not the official number, until confirmed.

Board-split appearances

Raw per-team appearance counts, split top 3 boards vs board 4 — the underlying data feeding the Rule 11(a) cumulative play-up pool used in the eligibility grid above (board 4 never counts towards that pool, for any team). For transparency/audit — expect this to be almost entirely blank until fixtures are played.

Nominal squads

Captains' nominal starting-point assignment for club planning — informational only, no bearing on eligibility. Players marked opted-out/unconfirmed are omitted here. Drifts over the season as new players appear, or the list is updated directly. Grade = current ECF standard grade, sourced from Derby CC's scraped ECF club roster, with a direct ECF-code lookup as fallback for squad members not found there (see scripts/derby_league_ecf_grades.py's log for exact coverage — a small number of squad members may still show no grade if ECF has no record under either their name or their code).
