(TSH-EDC). We ran 200 TSH-EDC trajectories -100 using the time derivative calculated as an overlap and 100 using the scalar product of the NAC and the velocity. With converged ensemble averaging and converged step sizes and if one sued the same velocity rescaling at hops, one would get the same result by these two methods so in that sense it is legitimate to combine their results; however, we ran these trajectories with both algorithms so we could compare the timing.
