@Christine20 Your active listings only display the reviews that those individual listings received. But your prior reviews and ratings are, of course, permanently attached to your user account/profile.
The whole "Superhost" business is not important at all, but for obvious reasons it accounts for all of your activity as a host rather than just the listings that happen to be active. It only uses data going back 12 months from each assessment date, so if your current listings are performing better, you'll have a better shot at it a year from the time you shut down the less successful listing.
