G claims we are 68% slower than all sites, yet I have done quite possibly everything I can to improve speed.

me too, but i'm just ignoring it. WMT has also suddenly started reporting a lot of 404s for pages which havent existed on my site for months and months, and they've never shown as errors before. so that pretty much proves that they are using old data from somewhere. maybe they are using old data on the speed tests too.
