The result of this pre-analysis shows a great disper-
sion along the parity line, and a total of 252 samples are
inside the ±15% dispersion range, with only two between
the ±15% and ±30% range and a mean error of 2%, dem-
onstrating that for the vast majority of the samples there
isn’t a significant difference between the SMC SG and the
Geopyörä SG. This indicates that there isn’t a bias in sample
selection between the tests.
In addition to the comminution results, whose ranges
are presented in Table 1, and the SG, the database is also
