Update the WDL model This PR updates the internal WDL model, using data from 2.6M games played by the revisions since f3bfce353168b03e4fedce515de1898c691f81ec. Note that the normalizing constant increases only moderately from 372 to 377. ``` > ./updateWDL.sh --firstrev f3bfce353168b03e4fedce515de1898c691f81ec Running: ./updateWDL.sh --firstrev f3bfce353168b03e4fedce515de1898c691f81ec --lasttrev HEAD --materialMin 17 --EloDiffMax 5 started at: Sat 22 Mar 11:02:14 CET 2025 Look recursively in directory pgns for games with max nElo difference 5 using books matching "UHO_Lichess_4852_v..epd" for SF revisions between f3bfce353168b03e4fedce515de1898c691f81ec (from 2025-02-28 09:50:59 +0100) and HEAD (from 2025-03-21 11:22:59 +0100).
