agreed!
the question is: what would be an appropriate value for the maximum allowable distortion? ie, if our randomization factor is 15 arcsecond at 0 wind 0 and 0 speed, what would make sense for it to be at 15 wind (sh4's maximum) and 0 speed? additionally, what range of randomization values would make sense with the boat at speed? ie assuming 0 wind, would it make sense to, say, double the distortion factor per bell to arrive at maximum allowable distortion? so (with 0 wind) at all-stop we'd have 15 arcsecond, @ 1/3 ~ 30 arcsecond, @ 2/3 ~ 1 arcminute, @ standard ~ 2 arcminute, @ full ~ 4 arcminute, and finally arriving at flank ~ 8 arcminute as maximum allowable distortion (again, excluding sea state)...
:hmm:
