My guess is that your route is already optimized. 105 miles a day with a majority of it at 45 mph is a good sweet spot. That's not to say you can't do better. Concentrate on techniques with the other 30%. Timing the lights, reading the lay of the land (uphill/downhill) and being at the right speed for the 25-30 mph section.
I've found that the posted speed limits have you at a terrible rpm range for good FE. Plus or minus 5 mph can make a big difference.
Most of all just keep at it. It takes time to figure it all out. Small will eventually turn into big numbers.
