My protein complex interface has a hydrophobic core and on each side of

Its experimental Kd is in nanomolar regions. How should I decide the
length of the simulation required in each window with this information.
As you would any other system. Look for convergence of observables of interest.
Your PMF alone suggests insufficient sampling for these simulations, so as
I've said several times, you probably need longer simulations to do so, but you
can start by examining the physical properties of each window. What you're
looking for is up to you, based on your knowledge of the system at hand.
