given by equation 73 closest to and lower than PSupp, in tonnes of oven dry whole soil per hectare.
MUB is the mass of oven dry whole soil associated with the sample, having the value of P given by equation 73 closest to and higher than PSupp , in tonnes of oven dry whole soil per hectare.
PSupp is the percentile value to which the ESM is set, specified in the Supplement
PLB is the percentile P associated with the sample used for MLB, as a percentile.
  PUB is the percentile P associated with the sample used for MUB, as a percentile.
Note: The sample used for MLB is the lower bound LB and the sample used for MUB is the upper bound UB.
 The equivalent soil mass:
              -  acts as a cap to the mass of soil for which carbon stocks are worked out (both in the first and subsequent estimation event). Samples for subsequent estimation events should target the equivalent soil mass set for the first estimation event.
              -  is intended to be set to the nth percentile sample weight (set in the Supplement), rather than average sample weight, to ensure that the mass is set at a rate that can be expected to be achieved around 90% of the time (everything else being held equal) in subsequent samples. This avoids underestimating carbon stock changes as a result of collecting a mass less than the equivalent soil mass in subsequent sample rounds.
              - may need to be recalculated for each layer (0-30 cm, 0-x cm) if sub-layers are excluded from calculations (for the purposes of equalising soil masses between estimation events).
              -  is defined for each 0-30 cm layer and 0-x cm layer within each CEA in a project.
