Are a few inch pounds over manufacturer recommendation the end of the world?
It depends... but you don't ever want to find out as once a fastener gets over-torqued it will never be able to retain the tension you need.
Again... perfect world... and most of what I'm talking about is really applicable for a much larger fastener application. Just look at head bolts and gasket compression and the sensitivity to retained tension.
And you're right.. its not a great amount... and all probably within the accuracy of some torque wrenches.
But it is something to consider.
