Default Focussing the eye piece

Setting up a scope and want to set up the eyepiece focussing. BFTA instruction manual says parallax at infinity, look at the sky, and twist eyepiece to get the reticle as black and sharp as possible. Two questions: (1) Is this still the best advice? and (2) Are there consequences of slightly bad eyepiece focussing?
Help appreciated.
