There is an amendment to the WHWS Sailing Instructions
It brings the scoring system to be fully in line with the RRS and the standard TOPYACHT settings. See here.
The actual published results on the website are in accordance with this amendment.
With respect to final series results, it is unlikely that any boats will be disadvantaged by this change.
However, if any boat thinks they are we will review and if required amend the final series results to ensure that is not the case.
