A guest can only rate a stay with a 4* or a 5*, and there is no inbetween. Hence, in order to remain a superhost you are expected to have pretty much only 5* stars, since if you get for example 10 reviews, you can only afford having a single 4* to retain an average of 4.8.
However, I feel that this is unfair given than there's no possibility to rate between 4*-5*.
In American standards 10/10, 5/5 or 100 marks are more easily awarded. In the European social culture, a full mark means perfection. Wheter it is at school or univeristy, in the UK for instance an A is anything above 70%, wherelse in the USA it's 90%.
So, my question, how can you realsitically expect hosts to remain superhost if they make it so hard ?
I always go the extra mile for my guests, wheter it's free pick up from the airport when they land late, free water fruits and snacks, giving them tips. Sending them messages with the current local events. It is very disppointing and deterring to go through all this effort and just get a mere 4*. It is becoming harder and harder to go the extra mile as for instance some French or Europan guests don't give a 5* easily - and this is due to their socio-cultural upbringing.
Please airbnb, bring back the option to rate 4.5* !!
