1. Penalty time is calculated as distance between time of first successful submit for the contestant on this problem and 0:00:00 01.01.2022, i.e. successful submissions at 23:50:00 31.12.2021 and at 0:10:00 01.01.2022 will both have penalty time 10 minutes (600 seconds).

2. Multiple Language Round rule: If for the first successful submit for the contestant on the some problem was used the programming language, which was never used by this contestant in his previous first successful submits on other problems, contestant receives language bonus: his summary penalty time is decreased by 100 minutes (6000 seconds). Note that different implementations of the same language are counting as same language, i.e. Java 8 and Java 15 are both counted as Java, C++ 32 bit and C++20 64 bit both as C++.

The coming Grand Prix of SPb happened to be in the same time with Codeforces Round based on Dasha Cup, with the Discover Riga and Discover Singapore camps by Moscow Workshops and with Izhevsk mirror of the Petrozavodsk training camp.

To deal with this issue:

1. For teams participating in the camps the mirror of the Grand Prix will be the part of the competitions for both divisions. The results will be added to the OpenCup standings as the official ones.

2. For other teams the Division 1 Grand Prix can be started virtually. Because of the experimental problems of special type the current Grand Prix will be held entirely on ejudge system. For Division 1 credentials are transferred from Yandex.Contest to the special server. Any team may start the virtual contest anytime before 11:00 Sep 22. For teams participating in the camps mentioned above using of this feature is prohibited.
