I have not done this type of experiments myself, however, I have seen
other papers that support the same claims as Caves et al.
The practice is that you run multiple MD simulations with different
initial random seeds -- so that each simulation starts with a different
initial velocity profile. This randomness will contribute to barrier
crossing and thus improve sampling efficiency.
Another trick is how to define "short" and "long." People may use 300
ps simulation as a "short" trajectory -- which in some applications is
