Abstract: Strategies are introduced for coherent measurement of pulsational waveforms, amplitudes, periods, and period change rates, where `coherent' means that the model stars indeed pulsate, with no artificial alternation between pulsation without binary effects and binary effects without pulsation. Capabilities of the more advanced eclipsing binary (EB) light curve models are in place, such as simultaneous solutions of multiband data and radial velocities with inclusion of tides, mutual irradiation, and proper datapoint weighting. An application to the Algol-type EB V1352 Tau exhibits possibilities.
