how does NC define vs HERO?

[AlwaysOnTop]

how does NC knows who is the hero?
If I play on a site and able to change the screen name. I think on the database it would be 2 Hero.
I would have 2 screen name. User1 & User2.
If a player 3Bet Hero 25% more often than average. How does NC define Hero? User1 or User2?
Is there a way to input Hero Screen name and tell NC who is the current Hero?

Thanks

There's no way to define a screen name = hero. In every hand history in which you played, there will be a line similar to:

Dealt to SretiCentV [Ad Ah]

That's how the hero is defined
