Hyperspeed EXTREME Page Speed

I used this app to help reduce my page load speed. Here are the results after 2 minutes of setup:
Average Site Speed (Speed Index) -37.2%
Average Google PageSpeed Score +52.3%
Total Blocking Time -46.2%
Entire Page is Completely Usable (Time to Interactive) -37.8%
Render Blocking Resources -35.7%
Largest Content Has Loaded (Largest Contentful Paint) -34.8%
Average Page Size (Total Byte Weight) -27.9% Again, after 2 minutes of setup!! And everything looks fine! One page I had wasn't previewing properly; and the support team addressed it in a few hours. All I had to do was a final preview check and publish.
