It it simply doesn't add up. 344w and only averaged 20 MPH. Either OP weighs significantly more than 280, was riding up a hill or had a terrible head winds. Or all 3 of them.
Is a 5 1/2 mph headwind considered "terrible"? That's all I had to put into that calculator you linked to to bring a 344W average for a 280 lb rider down to 20mph average.
Equally, I would sooner believe real world results than some estimate from an algorithm that is a complete black box to me. For example, does the calculator include such factors as increased drag big guys have over a 150lb rider?
I have no idea if @
Jarrett2's power meter is calibrated, however, his readings are not crazy IMHO.
