a.  Data record gives both 0.15 and 0.05 as flat cover estimates for these storms, so used average.
b.  Used wind data for storm on 5-02-91, soil collected on 5-08-91
c.  Observed and predicted soil loss includes storms on 3-08,09-92 
d.  Observed and predicted soil loss includes storms on 4-23,24,25-93
e.  Flat cover estimated after subsoiler and disk/roller tillage.               
             f.  Rain may have restricted erosion..
