Hi Patrick, the main point is that the values of CCwork and CCfree should be lower than those of CC*, but by as little as possible. Thus they are expected to decrease from about 0.95 at low resolution, to low values at high resolution - how low they decrease, depends on the high resolution cutoff (or rather, the data quality at that resolution).
Overall values are not meaningful anyway because even a completely wrong structure has strong Fcalc at low resolution, and weak Fcalc at high resolution. This means that a CC significantly above zero always results if a large resolution range is used for its calculation.
