Would a satellite that has a retrograde orbit and a shorter orbtial period than its planet's rotational period be tidally accelerated or decelerated?
In the first case, the planet's rotation will carry the tidal bulge ahead of the satellite,  this will tend to accelerate the satellite, causing its orbit to recede.  In the other cases, the planet's rotation will pull the bulge behind the satellite, causing the orbit to decay.  It doesn't matter if the period is greater or smaller in the case of a retrograde orbit. The bulge is behind the satellite, and so the orbit will decay.
