The pebbly texture of the RC paper may have something to do with that.
I've also found that a4x6 at 72 or 96 dpi from one of the jpegs from Fuji's own scans is completely inadequate, whereas as 4x6 at 72 or 96 dpi from one of my scans is quite acceptable, in fact it is as good as a 4x6 from a 300 dpi tif that I prepare myself.
