Some interesting statistics about the decisive opening pairs that ended 1.5-0.5:

0.33 / 0.67
0.40 / 0.71
0.40 / 0.91
0.41 / 0.86
0.43 / 0.98
0.42 / 0.79
0.42 / 0.64

0.65 / 1.15
0.55 / 0.84
0.43 / 1.34
0.52 / 0.90
0.52 / 1.48

These are the book exit evaluations by Leela (mentioned first) and Stockfish (mentioned second) in the opening lines that ended 1.5-0.5. Conclusion can be similar to the S19 superfinal: Leela book exits lower than +0.40 seem to be an almost certain draw. There were only two exceptions, where Leela blundered a drawish position after the book exits had been lower than+0.40.
