Yes to you last point.
Generally no to your first, because currently most operating that system run to a fixed adjustment point, either 2 weekly or monthly, so any change could incorporate a lot of scores!
I sort of understand where you are coming from with your subsequent post but would point out that in the first instance people won't all be changing courses, secondly this already exists to a degree when playing from different tees at the same course (and will even more going forward) and finally, you are correct that it won't actually make any difference!
In practice I anticipate things the other way round - the easy courses will be favoured because people will have their lowest playing handicap when playing them.
Not a comment on your observation - but that this will be what is going to happen is - in my opinion - just rubbish and not what handicap golf is about. I have a handicap means I have a handicap - and that handicap goes with me wherever I play. That's just how it is. From what I am starting to understand I am just hating the sound of the WHS...
