The trade-off can be difficult to calculate though. If I coast in gear then I use no fuel and with long gearing (30mph / 1000rpm - 6sp Diesel) I can coast for a long time and my MPG reads at infinity. If I coast out of gear I can go slightly further but then engine is burning fuel to keep going and MPG depends on speed, can be between 40-65.
I'm interested in working out whether its better to accelerate more strongly uphill that try to cruise for longer at a lower throttle, and also whether its better to be in a lower gear (less effort but more RPM) vs a higher one. My experimentation so far has not been conclusive.
