Since the title of this thread is cranksets, and since the OP's question is answered to his satisfaction, and while I have your attentions, here is a new question.

A crank designed for three rings puts the third ring farther out to the right than a crank designed for one or two rings: true or false? I put one of these cranks on my track bike. It has one ring in the position for the biggest ring, and he chain line is horrific. Putting on a real track crank should fix this, right?

Are the ring positions relatively standard for a given type of crank (single, double, triple)?
