I'm sending this as mostly feedback, I'm not sure if there's anything you can to do help. I'm a little disappointed that the "fixes" for things are turning out to be ads for your services. I've typically been getting around an 80 to 85 performance score on the sites I've been setting up the last few months, and this new one (which has much less page content on the home page than the others) came in under 50. The first "fix" suggested linked to your hosting service, talking about server performance. Other fixes talked about doing things I'd already done, like enabling browser and page caching. I ran the audit 10 minutes later, and now got a 74. I'm guessing that the score is largely affected by the network connection/speed, which of course has many potential factors. So far I'm finding Hummingbird to be the most frustrating and unclear tool. For example, under the section that talks about how I should eliminate render blocking resources, it lists a bunch of your CDN urls. Compared to plugins like Smush, this seems to require much more knowledge and invested time relative to other caching tools.
