Before revision:  By Langevin dynamics simulations of regular and modified translocation models  we find that an incomplete model, where the trans side is {\it   excluded, gives rise to characteristics that are in stark contradiction with those of the complete model, for which \alpha increases with f_p.
After revision:  By Langevin dynamics simulations of regular and modified translocation models we find that a previously reported incomplete model, where the trans side is {\it excluded, gives rise to characteristics that are in stark contradiction with those of the complete model, for which \alpha increases with f_p.
