Well, I've never seen a processor usage counter increment... but then again I've had only very little experience with hpux. Most often I'm use to seeing a processor counter that is a snapshot of %utilization at that moment, or as in the case of Cisco and some others, a 1-minute or 5-minute processor average. In which case the Gauge option is required. Since a this time of morning I can't seem to wrap my brain around how that counter you're polling is giving processor utilization stats, I'm afraid I can't come up with an answer for you. But if you really are trying to calculate a rate, I don't think that subtracting it from 100 is going to give you anything useful. YMMV - again I've never experienced a counter like that, but that doesn't mean it isn't legit...
