Here's how I interpret the BSFC charts. If you're on the gas, put it in the efficient zone. Approximately 1500-2200 rpm and ~75% throttle. In most cases that makes you accelerate. So you hold that zone until reaching the upper speed limit (either legal or self-imposed). Then go to neutral and coast for a while. I do engine-off coast which saves even more fuel. Then get back in gear (bump-start if EOC) and do another pulse. Repeat repeat repeat...

I find slightly better results at lower rpm - centered at 1700 or so - instead of the 2000+ the charts usually show.
