Space.com report said "The new paper, published online June 10 in the journal Astronomy and Astrophysics, showed that the objects in this system behaved as Einstein's theory predicts — or at least didn't differ from Einstein's predictions by more than 1.8 parts per million. That's the absolute limit of the precision of their telescope data analysis. They reported 95% confidence in their findings."

An excellent test of SEP here and supporting Einstein :) My note, see the NASA ADS Abstract, An improved test of the strong equivalence principle with the pulsar in a triple star system, https://ui.adsabs.harvard.edu/abs/2020arXiv200501388V/abstract, and the arxiv report attached. From the conclusion "As for Archibald et al. (2018), our results are fully consistent with the predictions of GR. This limit strongly constrains SEP violation and any alternative theories of gravity that predict a violation of the universality of free fall for self-gravitating masses (GWEP), particularly for neutron stars with masses similar to
that of PSR J0337+1715…"
