[DOUBT] Chess Insights: What is it and how does it work?

Greetings, friends of Lichess!

In my user profile I found a link labeled "Chess Insights - Analytics from your games"

When I clicked on it, I was redirected to a page with statistical information based on my performance through various games.

I have a feeling that I found a hidden treasure, but there are two things I don't understand:

1. I don't know what the purpose of this data is
2. I don't know how to interpret these numbers.

A user's manual with explanations about this tool would be very useful, but my main problem is with the language: all the texts are in English and I don't master this language.

Are there plans to translate them into other languages? I am interested in Spanish.

Thank you!

If developers are interested in making this page translate-able, issue github.com/ornicar/lila/issues/3160 has been recorded.

Truth be told, I don't fully understand this feature, although I suspect there is a good way to use it.

I feel this type of analysis is more useful to someone programming a computer than a human working to refine their game.

I find the win% and rating gain for different openings* very useful and it's one of the suggested filters as well. Very easy to spot weak openings that way. Most of the other is closer to fun stats, then useful stats. If you use it carefully you can find lot's of interesting things, but you would have to be mindful of the filters and careful with the interpretation.

*An example might be King's Gambit only giving you a 40% win rate, so you should learn it better or stop playing it etc.
