We analyze quantitatively physical effects that limit the coherent combining efficiency in highly nonlinear divided-pulse fiber-based setups such as parabolic amplifiers or nonlinear temporal compression experiment. The impact of differential dispersion and non-equal replicas power is assessed using numerical simulations and compared with experimental demonstrations. We also point out optimization strategies to minimize the impact of these effects on the performance of ultrafast fiber sources.
