Currently, OR doesn't show any decimal places in the aggregate and likely rounds to the appropriate whole number. This means all properties will show a "5" if their score is between 4.50 and 5.00; which is a huge range that likely includes 99% of properties. Every other ratings widget has a setting where the number of decimal places can be shown; it is a basic feature. It feels disengenous and not helpful to show a "5" when the real score is "4.98." Potential bookers will trust 4.98 more than 5, in my opinion. They can also go to the OTAs (e.g. Airbnb) and see "the real" score, and unless it is 5.0, they will not look kindly on the deceit of showing 5 (especially if the real score a lot lower, for example 4.51).
