I concur with your assessments on the games and reading comprehension sections. It looks like for those of us that had an experimental logical reasoning (LR) section, it's a bit tougher to figure out which two were graded.
I can't remember any single argument/question from any individual LR section; so I can't match any of my LR sections with any described by those individuals who only had 2 LR sections. What I do remember is that the LR sections were 1-3-5, and that the first seemed much much easier than the last two (even considering the fatigue factor). The last two LRs seemed to both be of equivalent difficulty, at what I would describe as between moderate and high.
If ya'll had only two LR sections, do you remember if one of them seemed much easier than the other? All other things being equal, this might suggest that my easy LR section was one of the graded ones, which would be pretty cool.
