Is there a conclusion of this thread? My read of it is that no amount of tweaking how you calculate the IID help the fact that in 59/62 bits you have a limited space to search. The Sec scheme does help, but increases costs equally for both attackers and defenders.
FWIW, I'm struggling to understand the draft. But I couldn't make it to the meeting.
