As promised, I am posting a calculator for calculating the tournament rating using two methods for all interested parties (non-linear rating, which takes into account only the lag behind the leader, and an oscillator, which also takes into account the player's ordinal position). In addition, the calculator presents an alternative method for calculating the rating for tournaments, where the criterion for victory is not speed (days), but the result (points, number of resources, or number of units).
The method of working with the calculator (Excel) is very simple and described in the file itself. In the future, it will be possible to add a calculation of the current rating, taking into account the aging of the previous result. And also, supplement the calculation mechanism with the rank of the tournament, which will be the arithmetic mean of the current rating of all players who participated in the
