I don't think we know exactly what is stated here.We 'know' from statements apparently based on initial FDR data (?) that three (immediately?) previous flights showed URA (UAS) tendencies. We don't know that they were investigated as each occurred. The infamous leaked MX log only showed a single write-up. It is surely possible that nothing was written up until the final flight of the day, so MX really only had one (overnight) troubleshooting attempt?
