How grades are calculated:

Lab users have asked for a single grade so the procedure will be that the grades for the four certified analytes (DM, CP, ADF and NDF) will be averaged (A=4, B=3, C=2, less=1), and then grades will be
assigned as follows:

B=Less than or equal to 2.4 to 3.4
C=Less than or equal to 1.4 to 2.4
Fail= 1.4 or less
