I think for the UK the list should read "courses Americans go to play at"
Glaring omissions are West Sussex and you've guessed it Royal Cinque Ports. Golf World mag in the UK do not use raters as such the panel are respected GCAs, county honchos, pros, top amateurs, etc. i.e those less likely to be flattered by a new place with an entertainment budget. It is the rating most Brits go by.
GW has West Sussex at 29 and Deal at 39 in GB&I
St Enodoc is 38, below us are Machrihanish, Swinley, Western Gailles, Old Head, Carne, StA New, St Georges Hill, Casle course, Rye and Tralee. Queenwood and StA Jubilee are not in top 100.
On these ratings West Sussex should be around 40 and Deal 55-65.
