Table 5: Mass loss from binary systems. N is number of the model corresponding to Table 3. $\bar \beta_{\rm fast}$ is the average accretion efficiency of the secondary during the fast phase of Case A mass transfer. $\bar \beta_{\rm slow}$ is the accretion efficiency of the secondary during the slow phase of Case A mass transfer taking into account matter lost by the primary only due to the mass transfer. ${\bar \beta_{\rm slow}}^{\rm wind}$is the average accretion efficiency of the secondary during the slow phase of Case A mass transfer taking into account matter lost by the primary due to the mass transfer and stellar wind. $\bar \beta$ is the average accretion efficiency of the secondary during the progenitor evolution of WR+O binary system taking into account matter lost by the primary only due to the mass transfer and ${\bar \beta_{\rm mtr}}^{\rm wind}$ taking also into account stellar wind mass loss of the primary.
