current return for max/min thickness is the thickest/thinnest unit in a given column. Recommend making this field the summed thickness of the max/min estimates for units in a given column
Due to my poor decision with min_thick format, this should probably be:
sum(max_thick) = max_thick
sum(min_thick) = minmin_thick
For all min_thick=0 substitute min_thick=max_thick then take sum: maxmin_thick
