I have some local code doing a similar thing to https://en.wikipedia.org/wiki/FIDE_Grand_Swiss_Tournament_2019 and will double check your imports over time too. Some further suggestions:

Additional name replacements (to avoid redirects, and in some cases, incorrect articles)

• Surya Ganguly -> Surya Shekhar Ganguly
• Matthias Bluebaum -> Matthias Blübaum
• Batkhuyag Munguntuul -> Batkhuyagiin Möngöntuul
• Mustafa Yilmaz -> Mustafa Yılmaz
• Jonas Bjerre -> Jonas Buhl Bjerre
• Swaminathan Soumya -> Soumya Swaminathan
• Quang Le -> Lê Quang Liêm
• Elisabeth Paehtz -> Elisabeth Pähtz
• Mircea-Emilian Parligras -> Mircea Pârligras

Additional name disambiguations:

• Ivan Saric
• Andrey Vovk
• David Howell
• Evgeny Alekseev
• Eric Hansen
• Robert Hess

Also should add in a "data-sort-value=0|0.5|1" after the style to allow the ½ to be sorted correctly. For example:
style="background:white; color:black" data-sort-value=0.5 | {{Hover title|Mustafa Yılmaz (TUR), 2595|½|dotted=no}}

Also suggest "Not paired" and "Bye" records to have style="background-color:lightgray; color:black"

@Griphomaniac Cool, thanks! I made all those changes (in the code and in the article) (except I stuck with "background" instead of "background-color").
