Think you may have placed this in the wrong forum.
Not a II member but don't believe there is a points chart for II. They, without the rental complication, are week for week exchanges.
The seasonal colours of weeks are available on the II website.
intervalworld.com, or

You may be referring to the demand index, showing the relative demand for weeks in an area, that is also available on the II website.
If you are referring to the few Wyndham resorts that use II as an exchange company Star Island, Governors Green etc then they are available to oursiders, probably checking ebay auctions where the charts are commonly published and exchange affiliation shown.
