Questions, answers, and resolution of disputes regarding the online rating in HoMM5.

Technically, it's possible, but I agree with this statement:

Because regular games are just like tournament games. I think everyone will agree that players prepare for ranked games just as much as they do for tournaments.

The difference with tournaments is the prizes and rewards. (We could create a thread about prize-winning places),
but tournament games are no worse than regular games (if they follow the rules or if it's considered that the players are playing with mutual agreement), so they are included in the ranking along with regular games.

Regarding doubts about the fairness, if you look at the ranking formula, you can see that with a difference of 500 points (which is currently observed between the top players and the middle), players with a higher ranking lose -35 points for a loss and gain +10 points for a win.
Players with a lower ranking gain +5 points for a loss and +50 points for a win.

Therefore, you fall down almost twice as fast as you climb up,
and you can also play against players with a similar ranking and get +30 points for a win and -15 for a loss, but a player behind, playing against a higher-ranked player, will overtake them because they will get +50 points for a win and +5 for a loss. :)

This explains the paradox of the player strongit (31 losses, but over 750 points) and most likely ArhLich (this will still be checked)
