Synthetic ETV diagrams for a q = 0.4 semi-detached system when the donor is the secondary star (step ≡ 1000 cycles). Squares and circles account for a conservative era (β = 1.0) either in the absence or in the presence of a transient disk, respectively. Upwardly pointing triangles (β = 0.9) account for a hot-spot-driven non-conservative era in the presence of a transient disk, while crosses (β = 0.7) and downwardly pointing triangles (β = 0.5) represent a non-conservative era where material escapes via the L3 point.
