I was looking for something like this too, would be super helpful to see the breakdown
Breakdown of attempted rated puzzles by theme in stats

On the left side of the screen, if you go to Puzzles > Custom, you can see a breakdown for your rated puzzles. However, the scores in this breakdown do not account for time penalties (you know how in rated puzzles, if you take too long, even if your solution was correct, you won't get 100% of the score). The other breakdown (which I was talking about in the first post but had been removed) did account for the time penalties.

I'm pretty sure both were the same percentages. The stats are being updated, so at some point that may make it back.

Nope, very sure they're not the same. I was bored enough to check this some time ago. In Puzzles > Custom, my score for the "Fork/Double Attack" is 59%, which is exactly what I would have if I had solved every puzzle within the target time. In the breakdown that was removed, my score accounted for time penalties and would thus be for sure <59%.
Nonetheless, thanks a lot for the information! Eager to see the new updates.
Hi all!
Not too long ago, if you navigate to your own puzzles stats page, you'd be able to see a list of themes for the rated puzzles that you have attempted, with the themes sorted by your own success rate in descending order. Personally, I found this quite useful, e.g. I learnt that I was making too many mistakes in situations labelled "Fork/Double Attack", so I made it a point to train myself in this particular theme using the unrated puzzles. As this list has recently disappeared from the stats page, I'm wondering if anyone knows whether this list is really gone for good.
Cheers!
