On the other hand if you had "8" how would you know if it's good or bad? It is not intuitive, especially if you keep adding more. And the scale needs to be changed regularly anyways because the criteria are not the same, so a 8 now would not even be guaranteed to be a 8 tomorrow. The European system already resets the scales after a while (for instance the new ones don't have a + yet) and it is not just about changing min and max but many things are reevaluated based on new knowledge, so an item that was B can no be D while another one that was C stays C. Be it number or letters it is a breaking change so you might as well go with the intuitive system that matches most people's intuition

On the other hand, today's system you're led the believe that A is good, when in fact A++++ is good and for certain things A is fairly bad. Further when you change the scales you can't compare old and new. Is my A+ rated fridge better or worse than a new A rated fridge. Is it worth me updating it? A system of 1 to 5 can scale upwards. Alternatively set A as the best possible score as allowed by the laws of physics.

> On the other hand if you had "8" how would you know if it's good or bad? It is not intuitive, especially if you keep adding more. You will know that, when measuring something, the higher, the better, for whatever definition of "better" applies (less CO2, less Watts, more good nutrients etc). If the scale changes, or the definition of "better", you now have "9" appliances, which will be better than "3" appliances with their 15 years old label still attached to them. With the current system you have to check "oh, it's A+ from 2017, I need to check the actual numbers anyway". And yes, I understand that those labels are mainly directed at new items bought right now, and only as "local" comparison. And that if you sell a "new" appliance today manufactured 5 years ago and the labels have changed, you need to update the labels on it. Still, it's cumbersome. You either update the scale ever 2 years or keep adding "+" for a while. EDIT: also, houses. those fuckers tend to last for tens of years while being sold and bought all the time in the meanwhile.
