I normally won't use an upgrade on a flight that doesn't have meal service or is less than 500 miles in length.
Some of the best upgrades I've done have been on the shorter flights:
ORD-DTW: 3.5 hours
CMH-ORD: 4 hours
and
ORD <--> LGA: up to 5 hours a few times
ORD <--> DCW: 4.5 hours
I'm guessing you fly mostly HI-CA routes, though?
