I opened a support ticket with SchedMD and David kindly replied saying: # yes your idea is correct the grpcpumins usage is decayed (at a # rate of PriorityDecayHalfLife). It can also be reset according # to PriorityUsageResetPeriod in order to allow jobs to run # against the association tree or QOS again. This limit only # applies when using the Priority Multifactor plugin. Thanks for the confirmation David!
