Well, voltage at the starter can drop pretty far, but 6V
is a bit of an extreme number.
However, it is worth noting that the goal is not
to "compensate" for starting issues to get the same spark
as always. The goal is actually to get a better spark
during starting to help the engine catch when the combustion
chambers are cold and fuel isn't well atomized.
A ballast system allows you to have big sparks at
startup when you can use them, without running those
big sparks (and high coil currents) at all times to give
reasonably point life.
