Song Yadong vs Umar Nurmagomedov

Song Yadong's 8-fight experience advantage (18 vs 10 fights) held true, but the algorithm limited the bonus to prevent over-rewarding Song Yadong for the expected result. Had Umar Nurmagomedov pulled off the upset, his experience disadvantage would have delivered a modest upset bonus.
