Abstract We undertake a comparison of observed Algo-type binaries with a library of computer Case A binary evolution tracks. The library consists of 5500 binary tracks with various values of initial primary mass M(sub 10), mass ration q(sub 0), and period P(sub 0), designed to sample the phase-space of Case A binaries in the range -0.10 greater than or equal to log M(sub 10) greater than or equal to 1.7. Each binary is evolved using a standard code with the assumption that both total mass and orbital angular momentum are conserved. The code follows the evolution of both stars until the point where contact or reverse mass transfer occurs.
