your specific question was answered... but i want to add something in general. when you fly any (!) helicopter under normal conditions, you will have the normal indications and performances. if something unusual happens, even though it is within the specified limits, i would be concerned straight away, like you have been with your question. there is no black&white in anything, e.g. your helicopter will not explode if you pass go to 111% torque.
i have two happenings to me where the helicopter was within limits, but indicated something very wrong: the first one was a reciprocating engine that was almost, but not quite, showing red line on the cyl head temp. the owner was interested in all the people waiting to do rides, and told me to continue flying. i was within limits, but the helicopter ended up with loosing horsepowers and thus decreasing performance in general. the second was a turbine, where one of the bearings were leaking. the leak was within limits of what the manufacturer specified, but the helicopter flamed out in flight after internal engine failure as a result of engine oil being dumped into the burner can.
this is scary! a helicopter pilot should have good knowledge of the aircraft, aircraft systems, the instruments and their interpretations, etc. i have met many pilots who had flown lots of hours on machines that they could not understand the instruments and how to interpret combining several instruments and/or indicators (e.g. b206: fuel pressure on 0 but no fuel pressure light)
the other side is being too cautious, sacrifying a mission (and lots of money) for nothing. a former colleague of mine made an pre-cautionary landing on an airport away from the base, because he had a generator failure - instead of shutting down unnecessary equipment following the poh, he delayed the return with several hours, had to start the helicopter again, and fly the helicopter back to base. this because he did not know the pilot operating handbook. for that reason, i do not blame him for landing. <img src="tongue.gif" border="0">
