NOTE: Loss factor in column H3 must be correct for each tie. Corrections in column K should be entered with the same sign as the accumulated difference in Column J. (ie. If Column J shows -9.181 then you would enter -9 in Column K, while if Column J shows 12.121 then you would enter 12 in Column K.)
