..........Not sensitive in very standard situations such a big veer of wind for example, or no specific wind dynamics, when one does not really need a routing toolto know what to do.
I have not delved into it more than that, but possibly higher speed boats have a relatively reduced influence of errors. Also, they (Imoca et al) seem to spend so much time routing and routing that it is difficult to imagine such thing done in a normal boat, except for personal intellectual curiosity
