[quote=solecondad] I've found true lean burn over extended periods of time, i.e. maybe 3+ miles of 40-50 MPH roads w/o heavy traffic and w/o any stops has come very close to equalling P&G over the same period. Then again, my tests are slighted as I only enter P&G or execute FASs on those same roads when traffic conditions do not allow for a steady optimal lean burn pace, i.e. they're worse conditions but yield equal results. If I've got all the space in the world and want to get from X to Y in decent time, I'm totally content with lean burn. Either method makes the same argument for hard acceleration, as it takes you into lean burn quicker and allows for longer tenure there.

I myself enjoy making use of both strategies depending on traffic. I know FASs shouldn't be recommended for the noob in heavy traffic conditions, but that's where I believe there are able to make the highest relative gains over other techniques. If traffic is light and speeds are right, I rarely reboot.
