I've posted it on Reddit before but just realized I can probably post it there aswell. I wrote a simple userscript for vlr.gg that takes map stats table from each team's page, removes everything but winrate percentage from that table and shows it on a match page just like HLTV does. Map names and percentages are highlighted for easier comparison. I made it just for own usage so code quality isn't something special, though it works and don't seem to slow pages somehow much.
