Seems to me that the perfect advance curve would be beneficial to power gains through the rpm range and that the only real advantage to locked timing is a cleaner low rpm (driveability) car. If we want max pressure at a certain crank angle throughout the rpm range, don't we have to light the plug at various points? Maybe the rpm's are high enough and the rpm band is narrow enough that full advance is all that's needed going down the track. For my foot brake bracket car it seems like the correct curve would yield more power, but who cares about a little better ET in a bracket car?

Am I way off here?
