SQR is used to test if google search results are "right" across most searches, not if a website is "right" in general. Rating of a site from the point of google relies on other data points like speed, support of https, links to the site (aka page rank) and a lot more. Have a look at the SQR Guide (PDF Link in my comment above) for examples how Google classifies information results. (Especially the YMYL - Your money or your life classification and Expertise, Authoritativeness, and Trustworthiness (E-A-T))
