Why is this necessary? commonInit will now be called twice, which is not good.

ok, I'll fix it.

The index passed here shouldn't be 0.
Here we're trying to determine the size of the longest possible popuplabel.
Therefore, we shouldn't get the pop up suffix at index 0, but instead the longest pop up suffix.

Why casting to an int here?
NSInteger index = (circleDot.tag - DotFirstTag100); would cause problems?

The commented out method on line 247 also needs to be updated with the new parameter index.
