RE: dipstick and tubes.

I would get too excited about a slight over fill.  When the engine is running if the truth is known there is probably only a litre in the sump at any time, the rest scattered through the engine.

Overfil comes when there is too much in the sump and the crank starts to splash in it.

Another sympton of under fill is going around a tight corner, usually to the left, and have the oil pressure guage fall away.

If as you say the measured amount takes it  to a point between the 2 marks then I would still fill it to the top mark as you probably have been doing all along.
