Hi Jimmy, I think we all go through dips in form for whatever reason, and for me, day to day can be varied.I note that you haven't been playing a lot lately, and you could be a little rusty - after a few days break my game is a little dubious.
Ensure that you follow the systems requirements, especially in clearing your cache,
A quick note for Duder - do the same as above and your average went up as you increased tiers.
It can be very easy to blame others but as Chris said, usually if you go back and retrace what you did, you can usually work out what went wrong.
