    I hope this is a typo - more mass gives slower decay!
    
    If RCS is indicative of true cross-sectional area, drag force increases with
    RCS.
    But the EFFECT of the force decreases with more mass of the affected object.
    
    Some examples are the Echo, Explorer 19 and OCS balloons, and spent rocket
    stages in orbits similar to the payload's (which hopefully are heavier than
    the empty rocket).
    A more important example is debris from explosions, that do decay reasonably
    fast.
