Do users really evaluate like that?
For me, it's pretty obvious that rating is arbitrary and depends on how optimistic/perfectionist/obsessive/etc. the reviewer is and that there is not much difference between 4 or 5 stars.

Obviously it's also more reliable in the context of other evaluations by the same reviewer which the platform has easy access to, i.e. if someone always gives 5 stars, then a 4 star review from him is much worse than one from someone who never gives 5 stars.
