the average number of moves per game in a season - I had 62 in S20 :-)

https://www.lichess4545.com/team4545/document/ledger-129/ (and Accuracy King, too)

Plan

• First, I need to be able to compile and update collated datasets for all games played in a certain league and other relevant league/season data. For the 4545, LoneWolf, and Chess960 leagues, this has been achieved for both games and other relevant season data. For Rapid Battle and Series, it's been achieved for games data, but not yet for other season data.
• Then I need to develop all-seasons stats reports, first by league, and then (possibly) across all leagues, using the current season stats report template as a starting point.

Caveats

• Need to be careful not to present stats based on Lichess server analysis evaluations as that has changed enough over time to complicate comparisons of eval data across different seasons.

Things to include

• All season winners and podium finishers
• Stats on total number of games played and results by colour by board/rating band
• Popular openings tables
• Top 10 games across all seasons by number of moves played and total time taken
• Top 10 games across all seasons by combined ACPL (all, excl. draws)
• Top 10 thinks across all seasons (but remember to manually remove stalls from the list)
• Top 10 “dawdlers/Grischuk’s Cousin” games
• Endgame stats inspired by 100 Endgames You Must Know
• Tablebase position stats
• Tactics-related stats (pending progress on automated tactics detection/reporting)
• Sacrifice-related stats (pending progress on automated sac detection)
• Longest consecutive win and unbeaten streaks (incl. and excl. unplayed forfeits)
• Notable checkmate patterns and their frequency

The all-time stats report or section would benefit from some general community stats, such as:

• Total games played (per league)
• Total participating players (per league)
• Players per season (per league)
• A chart of games played by week, shaded by league
• A result by colour by average rating band plot for all classical league games (4545, LW, Series)
• A result by colour by average rating band plot for all classical and rapid league games (above + RB and Series and maybe Quest too)
• Top 100 players by games played; could show each league in a separate tab

• games where both sides castled short, or both castled long, or castled on opposite sides, or neither castled. Doable in R.
• outcomes of games with opposite-sides castling. Will probably require some python-chess magic.

• Describe the bug

When you access https://rahulan-c.github.io/lichess4545-stats/ , scroll down, you will see a random `{=html} text appeared.

• Tell us how to reproduce the error

Steps to reproduce the behavior:

1. Go to https://rahulan-c.github.io/lichess4545-stats/
2. Scroll down to the near bottom of the page
3. See a random `{=html} text

• Expected behavior

The `{=html} text should not appear.

• Platform

I'm using Google Chrome version 114.0.5735.248

• Screenshots

• Start by replicating the original ledger dashboards that were first made in March 2021 (before disappearing). I'm not even sure they can be replicated though.

• Then present the same content in a more conventional report format.
