Fuel computer accuracy

I have to say, some of the threads on this forum, and the amount of responses they get, astounds me

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.)

Xyzzy, the fuel pump is in the tank. It mounts in from the bottom. If you look how it sits in there, the pump part of it can't be in the fuel a good part of the time as it sticks up. Not straight up, but angled up. You can see the angle on the parts diagram.
