Their advice isn't perfect but that doesn't mean I won't pay attention to it. Memory use and leaking isn't really covered in their page speed advice anyway, which is mostly about server side caching, image optimisation, css / js delivery. If there's any other decent page speed assistance I'd love to see it.
