Could you send us the link to your website (to hello@pagespeed.ninja or via support ticket at https://wordpress.org/support/plugin/psn-pagespeed-ninja)? We will try to analyse what may be wrong with its optimization.
And did you try to apply different settings presets (from Safe to Ultra)?
Note that PageSpeed Ninja is in beta stage and there may exist some issues (especially on javascript-heavy websites), but we are working on making it better and better with every release.

Denis, while this is not a good review (it’s pretty substandard and not at all useful) it’s not really something that needs reporting.
I’ve removed that tag.
