Effectively every curve is "starting from scratch". The only way I can think of using information from previous unsuccessful curves is that it's probably a Bad Idea to use the same s-value (well, it's a complete waste of time if the limits are not increased). The point here is that the chance of picking a previously-used s-value is infinitesimal, providing the "random" number generator on the system is reasonably behaved.
