I searched Leela website for some statistics about its self-training, the number of games it played with itself in order to assess its progress or to be able to predict whether it is going to win the next Sufi, for example, but I did not find any information.
What is the number of self-games it played before TCEC S19 or TCEC S20, for example? Where can this information be found? Are there any other characteristics to be used to measure its improvement?
