Seriously speaking, there's also a possibility that you evaluated the necessary Q-range on the admission that the relation yield is a constant. But it isn't, and it is not easy to guesstimate it. Generally, it goes down as Q goes up, but the question is - how fast.

One way (frequently used before launching large projects) is a dense set of spot checking runs (with many starting Qs and a span of 2000 or a 1000), followed by a spline (or better yet with normalization the by number of reported special_q's), and a guesstimate from experience with similar runs of what redundancy is going to be.
