Disc starts on Pit or Land determining SD2 copying ability?

Could it be that burners that can copy SD2 start on a land, while burners that cannot start on a pit, or vice versa?

Depending on whether you start on a pit or a land, the DSV should either go very high up or very low down. Is SD2 designed to compensate, by having a string of weak sectors, which either raise or lower the DSV by a lot, then compensate it, and either raise or lower it a lot in a way which reverses the first string and tips the scale the opposite way.

Is there any tool which will measure the DSV for a certain sector, either reading from and image file or the original disc?

A digital oscilloscope, maybe…

Hehehe…

Well, shouldn’t you be able to calculate it relatively easily with a RAW image and an EFM table, simply switching a state for pit/land? Thus you would be able to determine the DSV, either above or below 0, (Depending on whether a CD begins on a pit or a land.
