Have you done any coast-down tests to determine your Crr? At this speed rolling resistance is a big factor in the power curve.
In imperial units it looks like you are doing a 1/4 mile acceleration run from 0 to 45 mph--did you only shift once during the run? What is the time to reach 70 kmh for each of the runs ABC--from that you can calculate your power and relative fuel consumption compared to the blue lines on the BSFC chart.
Also you might want to make some runs at 30 to 50% load to see if the consumption is higher there and that the best economy peaks at 60% and not lower.
