By considering the degree of orbital circularity and synchronism an estimate of the degree of tidal interaction in the ellipsoidal variable systems is attained. We find that the orbits are (with a few exceptions) circularized and synchronized forP(d)≲2. The highly inhomogeneous nature of the ellipsoidal variable class becomes clear within the framework of analysis and we discuss the evolutionary status of the more extreme systems.
