The voltage readings you gave all sound to me like they are within 
reasonable ranges, but I'd like to hear more about what voltages you see 
while driving. So far, I don't see any reason to suspect a problem with the 
battery or the charging system.

So why has your gas mileage gone south?

You gave a good list of the things you've checked, including the SP wires. 
Did you check each resistance? Any chance that one SP connector resistor 
has gone open? That can give you an intermittent miss, which will suck gas.

Any sign of clicking relays when the engine speed inexplicably drops?
