It is based on a very complicated formula that is calculated by the best ten out of the last twenty rounds you have played. The courses also make a difference as they are each rated with two numbers, course rating and slope. Your handicap index is based on your score on a course taking into consideration the difficulty of the course, i.e., course rating and slope... with your history and knowledge of golf, I'm surprised you didn't know this.
In fact, this complicated calculation gives you a handicap index, not a handicap. The handicap index is used with the course rating and slope of each course to arrive at your handicap for that particular course... i.e., your handicap will vary a little depending on the difficulty of the course being played.
HHF yes it is not simple.The USGA system takes the best 10 cards from the last twenty cards. You then divide the sum of those best 10 and multiply by 96% ( i think this is the multiple) and this gives you your handicap. You should take into account what the course SSS is though as against par
For UK, Eire and very many other countries they use CONGU ( Council of National Golf Unions ) and nothing to do with the R & A. I suggest you google congu handicaps and it is all there.
This is a big and quite complicated subject so my comments are trying to help those golfers who have never understood the calculation
I have kept this simple by not going into course slope ratings, which for example are non existent in UK
