I understand the 'advice' in the book to mean that at the instant of making the mark on the paper, your eyes should be on the object (in this case the hand being drawn) and not on the drawing, pencil or paper. The idea being to see as accurately as possible the detail on the object.
My problem is that if I'm not looking at the pencil/paper, the marks it makes do not look the same as the detail on the object I am seeing.
So my question was meant to be... at the instant you are making the marks on the paper, are your eyes looking at the mark being made or the object being drawn? The book says look at the object, not the mark you are making - unless I have misunderstood (see the quote in the OP.)
