I made a tool to show the detail of points earned in multi and optimization puzzles, including code golf.
This is useful if you want to improve your rank, since you can spot where you miss the more points.
Here is an example with my profile: http://apps.rezonux.com/codingame/?user=3799c30a7f390b64b9430ff53613309e489451
You need to provide your “profile ID” which is visible in the URL of your profile page.
For code golf, your top 5 scores are shown since they add up for your global rank.
You can use the search to filter on specific puzzles or types (for example “golf” or “single”).
The points are computed according to this topic.
However, there may be some errors in my tool due to rounding or draws.
Please let me know if this is useful for you too
