In a carburetor setup, that is true, since in most cases your static timing is what you have during cranking as well. Unless you have a vacuum compensated system directly connected to manifold.

In the case of an EFI setup like Bob's, the timing map contains areas that are only active during crank, and others that take over during running. As cranking rpm is really slow, it doesn't require the same amount of initial as when the engine is @ idle anyway. And, the lower you have it, the easier the engine will turn before firing. This is because, as you add timing during crank, the combustion is starting sooner before TDC, which creates work on the piston as it travels upward.

In a modern EFI ignition map, you'd often see single digit values in the areas using during crank. Then once it fires, it goes into a different area of the map adding more timing closer to what we traditionally see in a carburetor setup.
