Revert "Filter out estimates"

This reverts commit 2fdc18b2c33fa947e854c354857d83d22e649f46.

Because we should correct at source (i.e. where the PD estimates
are being computed) and the fix breaks w/kg display because it
doesn't apply different limits for absolute vs w/kg values.
Filter unreasonable model estimates

.. basically where data is sketchy or doesn't have enough
   representative efforts the model will produce lowball numbers
   which are not meaningful and should be discarded.
