Although I usually don't weigh in on these types of discussions, I have to agree with Pat B on this one. An arrow properly spined to the bow it is shot from, should not touch the strike plate upon its release, as the paradox (arrow bending) will have the arrow bend around the handle, and not contact it. We all have bows with a mark or groove in the strike plate worn down from repeated arrow contact, but those marks are actually marks of laziness, as they indicate that the bow is being shot with arrows that have a higher than optimum effective spine for the bow. There are many ways to reduce the effective spine in this instance, but if the arrows generally go where I am looking, then I don't bother to tweak the set up any further - although my shooting might be better if I did. My 2 cents.
