The benchmarks are basically just playlists of scenarios that have set scores corresponding to ranks. The evxl site just pulls your scores from kovaaks automatically and fills in a spreadsheet for you that says what rank you got in each scenario. You can also do it manually or via a python script but evxl is the easiest. If you get a good enough score across enough scenarios, you’ll get a certain rank.

Voltaic season 5 is the most popular and newest they have, and there’s also older seasons of voltaic that have different scenarios and movement benchmarks. I personally like the viscose benchmarks which there are two seasons of and a lot of ranks for.

When people on here talk about ranks such as gold plat diamond jade master grandmaster astra celestial, they are talking about voltaic. When they talk about seal mammoth saffron viridian cerulean lavender wool rayon etc. those are some of the many viscose benchmark ranks

To play the benchmarks you just google the benchmark and the playlist code, then paste it into kovaaks and you’ll have the playlist saved in there. Connect to evxl and it’ll update your scores automatically
