When I got my insight in late July, it took me a bit to learn the tricks but I eventually got to where at the end of my 51 mile morning commute, I'd just top it off at 70MPG for the trip. Going home was a little less, probably because I was in a hurry 
Well this morning I managed to top off at 57 MPG. There was a stark drop off a couple of weeks ago where the mileage just disappeared. Colder weather? winter gas? I dont know, but where as I could easily drop into "the zone" and cruise at 70-75MPG, I now find it hard to hit 60. I've often just said the heck with it and ran as fast as I wanted, only to find that im going 15 MPH faster at a cost of only a couple MPG.
Heck the other day I was going 65MPH on a slight downhill at only 60MPG and LOOSING SPEED!
I know one problem im having is with the stupid IMA. It starts background charging at 2 bars below top SOC, and pulls the equivellant of 5 bars charge until its been on 1 bar from top SOC for a while. This absolutely slaughters my MPG, because to try to keep the car moving at 65 I keep dipping into assist, then the hidden charge drags me down, and I dip into assist. I get mid 50's best when this is going on. I know this for a fact because I have an ossiclloscope on the CMDPWR signal and can see what its doing with the IMA. Ticked me off to the point that I shut the engine down and coasted while I reached back there and flipped the breaker off, just so I could get it to stop charging, not for mileage, but because I was tired of fighting the gas just to keep highway speed.
I mean what is the point in having a Kenetic Energy storage system if the damn controller charges constantly to keep it at top charge? I cant get anything from regen, because by the time I get to stopping, the battery is full. I literally cant get the charge below 2 bars from top without it kicking in a hidden charge of 5 bars regen.
AAHHHH!!!!!
So this morning I said the heck with it, and still got 57MPG, a hair below my recent bests. Im thinking about just putting tape over the MPG guage until next spring.
