or from the same source as you cited

The Pareto principle (also known as the 80-20 rule, the law of the vital 
few and the principle of factor sparsity) states that, for many events, 
80% of the effects come from 20% of the causes

In Microformats this means that if a propery is used more than 80% of 
the time then it should be included in the format, this will result in 
the top 20% of all discovered properties making their way into the final 
Microformat.

Yes.
