It is sometimes desirable to post the results of tournaments elsewhere, or amend the results of a tournament after it has finished for "some reason"...
There is an opportunity to do that via the API and new links on the tournament download pages, because you can generate the TRF.
Lichess's two tie-breaks for Swisses are Sonneborn-Berger and Performance Rating. I've recently posted about an issue with Sonneborn-Berger. However, the TRF includes the ratings at the end of the tournament, which means when you import the TRF into other software, you get the Performance Rating calculated based on that rating.
There are two ways in which Lichess could calculate Performance:
1. Using the rating at the start of the tournament
2. Using the rating before each individual game in the tournament
Which is it?
For the purpose of reproducibility, my fingers are crossed that it is 1. If it is 1, is it possible for the TRF to include the rating at the start of the tournament, not the end of the tournament?
