docs: Capture ratio--ratio of upside to downside capture.
  
          Upside capture ratio divided by the downside capture ratio.
  
          Parameters
          ----------
          benchmark : {pd.Series, TSeries, 1d np.ndarray}
              The benchmark security to which `self` is compared.
          threshold : float, default 0.
              The threshold at which the comparison should be done.
              `self` and `benchmark` are "filtered" to periods where
              `benchmark` is greater than/less than `threshold`.
          compare_op : {tuple, str, list}, default ('ge', 'lt')
              Comparison operator used to compare to `threshold`.
              If a sequence, the two elements are passed to
              `self.up_capture()` and `self.down_capture()`, respectively.
              If `str`, indicates the comparison operater used in
              both method calls.
  
          Returns
          -------
          float
