One document states the number of logical ports per adapter is 80/160 and the other has 40/80 for EC85/86 (200Gb). Which is correct?

The September 2025 edition of PowerVM SRIOV FAQs paper indicates 80/160.  I attach the paper herewith.

I understand that the PowerVM SRIOV FAQs paper says 80/160 but the paper 

"PowerVM vNIC and vNIC Failover FAQs with updates for Power11 based systems" says 40/80 in the same library and updated about the same time.  So which is it?

My guess is that the vNIC Failover paper somehow was NOT updated for EC85/EC86 because other adapters in the same table have the same values in both papers. 

Let's hope that Chuck Graham or James Chandler (who I assume are authors of these papers) sees this thread as they may be able to provide a response as to the discrepancy of EC85/EC86 between the 2 papers.
