David, that's exactly right. For every timestep value, one can derive the
appropriate upper limit for the restraint constant in a somewhat
physically sound manner.
I am just not entirely sure what was the purpose of the initial question,
because
for infinite restraint constant, I'd just freeze

If you want
I think this can be estimated from a general physical argument. The
absolute max in my opinion should come from
4*pi*tau = sqrt(m/k), where m is the mass of the lightest restrained
particle in the system, k is the constant you seek, and tau is the
timestep.
The coefficient is four because of the

10 x period suggestion above.

Thanks Alex. But then, theoretically, is there no limit? All depends on
your system's content, right?
