Except the WHS would prefer that you did and because of that my club has decided to go with that...whether they need to or not - we are. All roll up scores will be included in our 20 and so gimmes gone. One reason the club gives - and that I like, is that it will be much harder to manipulate your handicap for banditry or low handicap vanity/preening.I don't see those problems at all. There is no requirement to put in all cards, but cards will need to be declared in advance if you plan to do so.
When it is up and running, you will just pitch up, and if it is a comp, check your playing handicap, play your game off the tees specified for the comp, usually the same ones as every other week, write down 18 scores, hand it in, clear off and wait for the committee to issue new handicaps that evening or next morning. After a little while you will get a feel for what the likely changes will be so won't even be surprised to often.
If you are a stats nerd, like me, you will have a spreadsheet with the last 20 scores, and little formulas running so you will know before you go out that you need to score a 82 to keep the handicap the same (because that is the score about to become the 21st oldest score and thus fall out of the last 20), and that any better will reduce your handicap, and any worse will increase it with a ceiling of 86 because that is the current 9th best score and thus will be promoted into the 8 if you don't shoot a better 8th best to improve upon it.
