  Glitching pulsars fall broadly into two statistical classes: those with
Poisson-like waiting times and power-law sizes, and those with unimodal waiting
times and sizes. Previous glitch modeling based on a state-dependent Poisson
process readily generates Poisson-like behaviour but struggles to produce
unimodal waiting times or sizes. Here it is shown that, when some of the inputs
to the model are modified, both classes of statistical behaviour can be
reproduced by varying a single control parameter related to the spin-down rate.
The implications for past and future glitch observations and the underlying
microphysical mechanism are explored briefly.
