Player rating for tournaments across all installments of Heroes.

It would be easy to add a multiplier that boosts a player's score based on the number of tournaments they've played, to avoid a situation where one player has played two tournaments well and stops playing, while another has both successes and failures, is active, but has a lower average score than the first... then the activity coefficient would gradually increase his score...

Don't rush... :)

There's no need to find out anything about him. He plays once - he's constantly in the ranking. If he doesn't play, the game counter stays in place, which means his rating isn't calculated over time, and the player gradually slides to the bottom of the table, even if he played well. For active players, the rating increases depending not only on their result in the tournament, but also on the number of tournaments (we'll make this parameter less significant, of course)... You'll never have to look for anyone. Everything will be calculated automatically and it will be much easier for you - there's no need to "age" anyone... The "empty" players will slide to the bottom of the table on their own... :)

All of this is, of course, just ideas and concepts, but it's too early to dismiss them... we just need to find the golden mean that will satisfy everyone...
