Yes, exactly. That's why they let you do ranges - so that you can cover the most common fees. Now where you might have an issue is if someone could make a case that you consistently over-estimated to a protected class (ie, to discourage applications), but if you take the high estimate and consistently, across the board come in at that price or lower, it shouldn't be a problem. But you do need to look at it periodically and get a realistic number - you can't just arbitrarily assign a high dollar figure to cover any possibility, it has to at least be based in factual data.
