Thank you Ryan, maybe I'll disable Autoptimize, clear my caches and see how it measures up on Gtmetrix just with the other W3TC and my CDN running. As has been said before it's an area that just breaks things but for amateur bloggers who rely on plugins with a bit of self coding occasionally it's a scary and complicated topic - especially when writing to databases gets mentioned. I find it really interesting though. Thanks again.
