I don't really know much about how the scoring system works, so I forwarded your post. Here's the response I got:
His site has a ridiculously good page speed of 92, which I would point out to him:http://gtmetrix.com/reports/www.wildlifeabatement.pro/uNNLiYAi
The only problem I see is the page load time of over 17 seconds, but that?s his server response time, not the theme.
This is really on him if he wants to make further changes, we don?t guarantee a certain page score. He can optimize the css files if he wants, there are plenty of css optimizers out there, but he can?t combine them into a single css file; nor would you want to. We don?t optimize it by default because most people like to edit the css, and optimizing it makes it nearly impossible to read.
