One of the mysteries of the Okubo-Zweig-Iizuka (OZI) rule is that it is characterized by a scale {Lambda}{sub OZI} that is small compared to a typical hadronic width {Gamma}, whereas unitarity would lead one to expect {Lambda}{sub OZI}{similar to}{Gamma}. We show that while {ital individual} virtual decay channels contribute to OZI violation with this expected strength, the coherence between all such channels can conspire to make {Lambda}{sub OZI}{much lt}{Gamma}, as observed.
