Frequency versus Cover Chronology

I understand that some journals actually use words in their titles to denote how often something is published....like Journal A Weekly, Journal X Quarterly and et cetera. I think, however, that some publishers think that frequency related words in the title are not tied to how often something is published. In general, I try not to pick on individual titles, but there is a math journal that is titled "______ Quarterly" that publishes 5 issues nearly every year. Then there is the classical journal (also called "quarterly") that publishes only 2 issues per volume. My favorite, though, is one in the management field that is called _______ Quarterly, but publishes 6 issues per volume. Have these publishers not heard of special issues? And shouldn't they change their titles to reflect the scope of the journal (as well as the frequency)?
