I had an idea: I suggest adding a bonus to the rating calculation for players who upload save files (either before a battle or intermediate save files).
In this case, we need to determine the number of bonus points.
For example, the scheme could be as follows:
The winning player receives an additional 10% of the rating earned as a result of the victory for placing daily save files or save files before the battle in the report (approximately 5 bonus points). If both types of save files are placed, an additional 15% of the earned rating is added.
The same applies to the losing player. The rating loss as a result of the loss is reduced by 10% if one type of save file is placed, and by 15% if both types are placed.
In any case, placing save files is not mandatory for the game to be included in the rating.
