Mazda CX-7 Fuel Gauge questions

Last night I filled up the tank after driving with the light on for about 30 miles.
 
I only managed to put 14.50 galleons. This meant that there was 3.7 gallons in the tank when the light came on.
 
HOWEVER, the gas icon remained on and when I re started the car this morning, the icon was still lit!!!

Well, it might be that it is a slow starter. After all, it had a hiatus for three months when I was overseas and perhaps it is now only catching up with the rest of you.
 
Truth to tell, I really have little to complain about, save for the two main items. Poor shifting pattern and gas mileage. I hope that both will be addressed when I have my 5k checkup.
 
However, as you claim to be a "Technical Expert", (see your remark in an earlier posting), If I drive in auto and use cruise control more often than not, how does "Fuzzy Logic" enter into this?

Which posting did you read, that said I was a technical expert?

It might be interesting to take your Darth Vader into Mazda service and have them check that "doo dad" that keeps track of all of your CELs. They be able to figure out why it comes and goes.
  
You can tell I'm very technically oriented

Sorry if I have changed Technical expert from Technical oriented. Didn't mean to give you a swelled head.
