I was basing my calculations on a single token. Did 4 MB token > ring have multiple tokens? I don't know; I think so. But the saturation was certainly calculated on segment-to-adressee. In general you can assume 50% saturation (50% will be above the halfway mark, and 50% below), on top of which you can add 100% utilization (instead of 85% -- see Knuth on "hashing").
