                                         how to calculate a YG using
      es of backfat (Table 1).

      es by 0.3 in.2. For each 1 in.2
      more than the required REA,           •PYG = 3.0
                                            •Required REA = 12.2
      subtract 0.3 from the PYG.
      For every 1 in.2 less than the
      required REA, add 0.3 to the
      PYG. Below are  two tables                             Are You Tired...
