Interesting.  What does 'non conclavist' mean?  Why did he include 'st benedict center' under that?  They are indult/novus ordo; I know many of the religious personally.  I don't think they belong on this sheet, but other than that, it's very good.  Most of this information is new to me.

Non conclavist means that they hold the position that the See is actually vacant and have no defined plans to elect a new pontiff. If you notice, the conclavists are those who recognize an existing "pope" somewhere or have defined plans to have a conclave themselves.  

You are correct that St. Benedict Center is NOT sedevacantist.

Bishop Kelly and the SSPV aren't really sedevacantists but based upon positive doubt surrounding the status of the post-conciliar papacy. They make no position this or the other on whether they are True Popes like the CMRI does. CMRI is also very anti-Feenyite, posting in their chapels and many other places that Feenyites are barred from receiving the Sacraments in their chapels.

What about the resistance priests that were in the USML? The Institute Mater Boni Consilii of Bishop Geert Jan Stuyver.

I do not see the sedeprivationist "Instituto Mater Boni Consilii" in Italy.

It is referred to under Bishop Stuyvert but not as its own branch.

Aren't they (St Benedict Center) full Novus Ordo and hosted by the new-diocese?

Yes and no.  Depends which group you're talking about (there used to be 3).  All have come under the diocese in the last few decades but they do still think of themselves (falsely) as 'trads' because they prefer the latin mass.

So, at first glance, is this meant to depict SEDEVACANTISM (drawing out the permutations of sedevacantist theological positions) or to depict SEDEVACANTISTS?

So it labors under an identity crisis.

So, for instance, different SEDEVACANTISTS are show who happen to have the same theological groups, but only different in terms of being part of different organizations.

As I pointed out on another thread, sedeprivationism is NOT strictly sedevacantism.  In fact, Father Ringrose emphasizes that point.

SEDEPLENISM -- See is occupied simpliciter.
SEDEVACANTISM -- See is vacant simpliciter.
SEDEPRIVATIONISM -- See is occupied secundum quid and See is vacant secundum quid.
SEDEIMPOUNDISM -- See is occupied secundum quid and See is vacant secundum quid.

What's interesting is that certain SEDEPRIVATIONISTS, like +Sanborn, will EMPHASIZE the vacancy part, while others, like Father Ringrose, will emphasize the occupancy part.  So the difference is merely a matter of emphasis.

Father Chazal opts to put SEDEPRIVATIONISM under SEDEVACANTISM, but that's not strictly true.  It's actually in between the two somewhere ... just as his own SEDEIMPOUNDISM is.

This chart is quite bad, not sure where he got his information from but they're so many errors. 
Fullham is dead (RIP)
St Benedict Center (all 3) have been approved by their diocese to one degree or more.
He made conclavism 50% of the "chart".  Less than 1% of sedecavantists are "conclavists".  
He didn't differentiate (as ladisalus pointed out) between sede vacantist and sede privationist.  
Left out IMBC which has like over 20 mass centers in Europe (I think around 10 just in Italy)

Those are just off the top of my head.
