Fuel computer accuracy

[Xyzzy_imp]

I accidentally had to push the range on my CB today. The reserve counter counted down to zero and then it displayed a dash, and I still pushed on. In the end, I went 205.4 miles and used 3.35 gallons of gas for an average of 61.3 miles per gallon. The bike computer told me that I had used 3.4 gallons so that seems very accurate. The service manual tells me the 2014 "standard" fuel tank is 3.86 gallons. I don't think I could have pushed it much further because I think the fuel pump is submerged in the tank and needs fuel to cool it. (I might be wrong on that.)

My ride today was a mix of stop-and-go traffic, 70MPH slabbing and 50-60MPH back roads. I am very satisfied with the fuel economy that I am getting. I notice that the bike needs 10-15 minutes to warm up before it starts getting really good economy as displayed by the instant fuel economy readout. I typically get 65MPG at 50MPH, 60MPG at 55MPH, 55MPG at 60MPH, 50MPG at 65MPH and 45MPG at 70MPH. (At 105MPH I get a steady 22MPG.)
