I didn't look at the other one but NGC1052-DF2 is consistent with MOND: Original sigma = 7.8 (+5.2/-2.2) New sigma = 8.5 (+2.3/-3.1) "Crude" MOND sigma = 14 (+4/-4) https://tritonstation.wordpress.com/2018/04/04/the-dwarf-galaxy-ngc1052-df2/ https://tritonstation.wordpress.com/2018/04/04/the-dwarf-gal... And keep in mind these uncertainties are arbitrary cutoffs... Also, others claimed the distance they use (20 Mpc) is wrong. It should be 13 Mpc and this throws off the calculations: https://arxiv.org/abs/1806.10141 https://arxiv.org/abs/1806.10141 I see them still using the 20 Mpc value without addressing those concerns.

Thinking more on this... Those are either 90% or 95% confidence intervals (couldn't tell from the recent paper). So that would mean if you looked at 100 galaxies you would expect 10 (or 5) to fall outside the range if the model was correct.
