Not sure why this crashes for me:
/home/xbolva00/.local/lib/python2.7/site-packages/scipy/stats/stats.py:308: RuntimeWarning: divide by zero encountered in log

  log_a = np.log(np.array(a, dtype=dtype))

/home/xbolva00/.local/lib/python2.7/site-packages/numpy/core/_methods.py:75: RuntimeWarning: invalid value encountered in reduce

  ret = umr_sum(arr, axis, dtype, out, keepdims) 

Anway, I used --filter-short.. I ran and compare it 3x..

Yes, noise a bit but I think there are some stable improvements..
