Statistics: figures and conclusions.

You don't need to be a genius to understand that you can't separate the rankings. The HotS system doesn't understand the differences between them. To make some kind of separation, you need to change the HotS reporting system, which is problematic at the moment.

I'm not talking about separating the ranking; I don't need it in principle (plus, it's clear that if a player plays well in one version of the game, they can probably play just as well in the other).
When we submit a report, we enter the game version. It's true that it's not displayed afterward, but I really hope it's written somewhere in the database. And to make a distinction, as boovli pointed out, you can simply add a column to the table. If, of course, it's not written to the database and the field is just decorative, then yes, that's a shame.
I said that statistics compiled for both versions of the game at the same time reflect the "average temperature in the ward," showing some kind of overall overpowered element or overall weakness, but if someone dominates in one version and sucks in the other, and vice versa, then it will look average, even though it would be important to understand where they dominate and where they suck.
Something like that.
