I’d prefer to see an alphabetical order or even reverse alphabetical while having the same number as there have been Opens still seems a valid approach.
Not picking on any particular clubs or courses but regarding some dropping off and others being added, well, firstly it’s Rans list not ours and secondly, the ethos of clubs and courses changes and if a certain club or courses ethos for some reason no longer coincides with Rans criteria then fair play if it falls off. Similarly if a club or course changes its ethos reverting to be in line with Rans criteria then adding it seems valid.
We must also remember the words of the prelude to Rans listing.
