I recall reading (or perhaps talking with a Honda tech) who said there is a modest safety margin with regards to overfill that is applicable to the car. It sounds like
you aren't in any danger with just a nip over the mark. FWIW, reading the levels on this car is not the easiest thing to do but you'll get the hang of it. Just use the low side of the stick as your indicator and check it twice before deciding on where you're at. I double check before adding just to be sure. It doesn't help that I use synthetic (don't use synth until at least 7500 miles) because it's so clear. I usually lay it crossways on the towel just to be sure of the marks. Very clean.
