This is based on the required minimum you set (Required minimum quantile:) and is a calculated value Q(Evd) = (Arithmetic average of spot-check Xm(Evd) – Required minimum quantile) / Standard deviation s (Evd)

The test (Q>0,88) has failed. This comment identifies whether the test is within acceptable parameters compared with what you have specified (e.g. 25 MN/m²) or not. Again, it’s a calculated value.
