[meteorite-list] howardite vs. eucrite classification

[steve arnold]

Good morning list.How is it determined to distinguish
a howardite from a eucrite?I know it is the 10% of the
dioginite count,but how is it determined as the exact
percentage?Like Nwa 1929!HOWARDITE or EUCRITE?What
makes 10% the number count?
