You see, our tournament is only being held for the first time, so the rule regarding additional information may not be perfect, but its meaning is clear: if a player is suspected of cheating, they may be required to provide additional save files with a detailed description of each day (basically, something like that). After the tournament, this rule may be refined.

You understand, it turns out that only fast results are being suspected of cheating, but why not suspect slow results?! I'm exaggerating. One player completed it in 2 months, another in 3. Both are far from the prize-winning places, but maybe the one who completed it in 2 months was cheating unsuccessfully, and wouldn't the one who completed it honestly in three months feel bad? I suggest refining the rule regarding the announcement of results and checks. Fanat, browse the topic; my suggestion is there. The essence is that the preliminary results should be announced immediately after the submission of save files. At the same time, a list of players who must send additional materials for verification should be published, indicating WHO and WHAT specific materials are required. These players must confirm their willingness to fulfill these requirements within the time frame set by the judge. And only after that will the final results be announced.
This is practically the same as what you write in your post. I personally am in favor of this.
