Konrad,
Just like for RPM Master stats, didn't we want to call these just "stats"?

Description is okay, but you ignored the rest.

This is a friendly reminder during the review process.

It seems my previous comments were not fully addressed. Maybe my
feedback got lost between the quotes, maybe you just forgot to apply it.
Please go back to the previous discussion and either implement all
requested changes or keep discussing them.

Thank you.


Best regards,
Krzysztof
