Note to self: remember to re-download the guidelines every once in a while. This has been in my mind for ~3 years and they have changed them (for the better mostly!) a couple of times. A clear example is that now you don't need to have the high skill visa for the given time, but you just need to have the points for the given period (and even that is a bit ambiguous, it says you need to have the points at the time of applying and 3 years before, but it doesn't say "for the duration of those 3 years")
