First, practical advice -- don't use them! Second, when you use them in redistribution, remember you are redistributing from another protocol that doesn't collect the (E)IGRP statistics. So, at best, you have to approximate the values at the entry to the (E)IGRP command. Third, when you configure them with metric weight, you are specifying weighting coefficients to be applied to the dynamically measured information. The best writeup I know is in Alex Zinin's book, Cisco IP Routing.
