You should probably look at your PRs more closely, see #2357
It's frustrating trying to help when contributions are overlooked.
Anyway, I think you should probably have taken my approach, since asserting on 10th digit floating point value from a possibly fickle server math solution isn't particularly robust. You're testing the Python api, not the algorithm that the server uses to compute.
