The link reconfims what the other links said.

<the nominal expiration date is 20 years from the earliest non-provisional priority claim upon which the patent is based.>

If on the continuity page it says that a patent or application is claiming the benefit of some other patent or application, that means it is claiming the priority date of that other patent or application. IMO. Corrections welcomed.
