Yonik Seeley commented on SOLR-10082:
-------------------------------------
After removing the rounding, I'm seeing much larger variations than I would
expect for distrib vs non-distrib. As an example:
'74.7'!='74.66666666666667'
At this point, I'm not sure if the numerical methods used here are that
unstable (squaring big things can tend to swamp smaller contributions), or if
there is another bug somewhere that the rounding was obscuring.
