Practically perfect in every way
not really good or bad tbh, but interesting, if your nitrates in the tap water are 50ppm, then you'll never get them below that with water changes. 50ppm is no big deal really, yeah 'ideally' it would be nice to be a touch lower, but it shouldn't cause you any harm. some areas like london for instance have very high nitrates and plenty of fishkeepers manage alright.
on the plus side it means your maintenance routine is just fine
