Can someone add the experimental result of gravity on antihydrogen atoms?

CERN's ALPHA-g experiment has published data on gravitational behavior of antihydrogen atoms at https://www.nature.com/articles/s41586-023-06527-1. CERN declares that antimatter gravitationally behaves the same as normal matter. But the result is 0.75g+/-0.13g+/-0.16g, the average gravity is only 75% of normal gravity, and all data points show the average gravity is lower than normal graivty. Per my theory, 12.5% of antihydrogen atoms experienced repulsive antigravity while 87.5% experienced gravity, giving the average of 87.5%g-12.5%g=0.75g. See my paper at https://www.researchgate.net/publication/376171433_ALPHA-g_Experiment_Gives_Experimental_Support_for_Repulsive_Antigravity Hongdusocal (talk) 23:17, 5 January 2024 (UTC)
