OP, this is normal behaviour. All speedometers read slightly higher than true road speed (and this is further exaggerated at higher speed) so the needle being 2/3mph over the cruise control marker/set speed is normal and you have no issues.
Whatever you set your cruise control to (80mph say) - you will do this speed with your needle reading somewhere around 82mph.
That doesn't make sense to me. I think we all can agree that speedometers are "optimistic" in their displayed speed, but in that case why wouldn't the cruise control marker also be optimistic? It would be confusing otherwise. If I set my speed to 70 mph via cruise control, I want it to hold a set speed of 70 mph on the speedometer with the cruise control "target" lining up with 70 mph, irrespective of my true speed being 67-68 mph.
