How does that work? If you go up you will spend a lot more time away from home than you do now.
To talk through my match day process, during the game I note down everything that could contribute to an above standard or below standard mark. And I do mean everything, including every foul, who committed it and what the time was.
When I get home I assign every point in my notes to competencies, and sometimes they can be relevant to more than one. I then start writing the report, if I have no timed evidence for that competency then by definition it is standard expected and 7.0. If I have timed evidence I then have to decide for each competency whether that is a standard 0.5 increase / decrease or whether it merits more than that. That derives a mark at the end of it, and almost always it "feels" about right. When it hasn't felt right I've usually ticked the wrong box and can go back to correct it, or it has been a game where absolutely nothing has happened.
Is it fair? Not completely, as if you are on a game where there is no PI, no RP, no dissent, no SPA, etc, it can be very difficult to get noticed. But equally the old system wasn't fair, where some observers were giving 80s and other 70s for the same type of game and performance. I would argue the current system is much fairer, and I speak as someone who averaged 79 and didn't go up (and I can assure you my toys got chucked out of the box on that occasion so I know it is frustrating)
