The brushout method had nearly 40 per cent of the results more than 10 per cent
away from the mean, while over 60 per cent were more than 10 per cent away
from the mean for the cryptometer. If, however, the test results were reduced to a

2.3 An inspection of the data ( see Table I ) shows that for the low values of the
cryptometer readings, even a slight change in cryptometer reading results in a
very large difference in the opacity figure. This clearly shows that cryptometer ...
