I've done some more debugging on this, and I no longer think it's an off by one error. The reason is that they are only sometimes off by one (but...

@ev-br could you please take a look at the difference between ``np.searchsorted`` and our ``find_interval_ascending``? I've sunk quite a bit of time into it and can't get the two outputs...

@mdhaber I think this is nearly ready, could you take a look if you can re-run the CircleCI test - apparently I don't have the right permissions to merge the...
