Living 'dahn sarf' in England and being a member of a Scottish club (my only membership), I've also had many issues with folks looking at the 'validity of my handicap'. Under the old system, I would have to submit a minimum of three cards at the Scottish club to maintain my handicap. I used to do this by getting as many in as possible during my annual 'two weeker' in the highlands. Was this a fair reflection of my handicap for the rest of the year? No, but it's all I could do. it didn't make me popular with my good lady either but needs must. Come the advent of WHS, I saw the best of eight, of your last 20 as a reasonable method, and once I'd got my head around course ratings, slope ratings, PCC etc, I can pretty much know, how my index will be affected by any card I submit, even for nine hole games. I think it makes a decent fist of reflecting you on your better day, but like the old system, it can be abused. With what Paulboy described, it would have to be a handicap committee monitoring things to stamp out obvious abuse/cheating. I was very excited when Golf Scotland released their app so that I could submit GP scores from anywhere in the world (40k courses Ala Bushnell) Not being anywhere near scratch, I saw this as excellent as I could now submit every time I played, ensuring that my index would now be a true reflection of how I currently play. Then Golf Scotland committed the ultimate IT sin, by upgrading the software provider for the app. This meant getting something that looked marginally better, but had none of the functionality of the old app. Overnight I went to only being able to submit GP cards, so long as I was playing a Scottish course, and as long as it was verified by someone with a Scottish CDH member number. Any time I was contacted by someone from Golf Scotland I was mysteriously struck with Tourettes. In April, I was in Scotland but still couldn't submit GP scores as my playing partners are all Golf England members 🤷♂️. So yes, it's nice to now be able to recognise courses in the rest of the UK but still beggars the question, when will the UK golf organisations recognise that the 'W' in WHS stands for World?
