Karl Wright commented on LUCENE-7179:
-------------------------------------

+1 to that.  You can't create numerical instability because you do the same 
exact operation multiple times.


> GeoPoint and LatLonPoint test data should quantize once

> {{LatLonPoint}} and {{GeoPointField}} tests pre quantizes test data to ensure 
> consistency with indexed (encoded) data. The pre quantized data then becomes 
> indexed, undergoing another quantization. To guarantee numerical stability 
> this should be changed such that the test data is quantized after indexing.
