Some test cases for strongOA/weakOA

I am still – honestly – completely unable to work out what the proposed boundary between strongOA and weakOA (see copious blog posts recently) . I therefore put forward some testcases and ask those who understand it – especially the proponents – what category they fall into:

• CC-BY
• CC-NC
• Springer Open Choice from the site:Springer operates a program called Springer Open Choice. It offers authors to have their journal articles made available with full open access in exchange for payment of a basic fee ('article processing charge').
  With Springer Open Choice the authors decide how their articles are published in the leading and well respected journals that Springer publishes. Springer continues to offer the traditional publishing model, but for the growing number of researchers who want open access, Springer journals offer the option to have articles made available with open access, free to anyone, any time, and anywhere in the world. If authors choose open access in the Springer Open Choice program, they will not be required to transfer their copyright to Springer, either.
• ACS Author Choice ; from the site: ACS AuthorChoice facilitates unrestricted web access to your published ACS article—at the time of publication—for a one–time fixed payment, provided by you or your funding agency. Contributing authors who are ACS members and/or are affiliated with an ACS subscribing institution receive significant discounts. This policy also allows you to post copies of published articles on your personal website and institutional repositories for non–commercial scholarly purposes.
• The NIH Public Access Policy [which] ensures that the public has access to the published results of NIH funded research. It requires scientists to submit journal articles that arise from NIH funds to the digital archive PubMed Central (http://www.pubmedcentral.nih.gov/). The Policy requires that these articles be accessible to the public on PubMed Central to help advance science and improve human health.
• Green self-archival of a final author manuscript  in toll-access journal with copyright transferred to publisher
  
• articles published describing work currently funded by the Wellcome trust

The following terms have been proposed as synonymous with strongOA:
transparent and self-explanatory (Harnad):
RE-USE OA
READ-WRITE OA
PERMISSION OA
generic
EXTENDED OA
EXTENSIBLE OA
FULL OA
PMR: I am particularly worried about the use of "FULL-OA" for anything that isn't.
To recap – I now have no idea what the boundaryline is. I hope some testcases will make it clearer. Because everyone except me seems to agree the line is clear but I suspect they will all put it at different places.
