And, one does not need to guess at how much "a lot" is; the legal
community uses a ruling from 1947, issued by Judge Learned Hand in
the case of United States vs. Carroll Towing Co., to determine how

might have provided quantitative data to researchers), its very hard
to calculate estimated damage.
