I suggest trial and error in quite short runs without wasting time on waiting for next day or so. Really large k can create segmentation faults or "cannonball into wall" like effects in MD movie.

I took Justin Lemkul's tutorial as the guiding script and started with k1 value of 1000. As it seemed, it needed more force to detach the molecule from its binding partner. Can you tell me how to estimate/calculate this value or it simply based on the trial-and-error method? Also, what problems can take place if the value is large (huge, I guess)?
