A number of type III groups is studied. Wave particle interactions are neglected and the so called drift approximation is used to model the electron beam evolution. We extrapolated the observed Flux-Time profiles towards higher frequencies and estimated the injection time for the individual beams responsible for the excitation of the type III's. A simple clustering algorithm, based on the temporal separation of nearest neighbour injections as a proximity criterion, was used to identify patterns of burst subgroups within the type III groups. The question of whether the acceleration and injection of component bursts exciters is coherently modulated in a single source, or this process is driven by a statistical flare in a spatially fragmented energy release site, is addressed.
