Good question (and good catch on that post)! I actually hadn't looked at that article in a while: one of the upsides of the current/updated Student Centers, including Analytics, is that people seem to find them a bit more intuitive and user-friendly than the prior setup, so we don't get as many inquiries as we once did.
That said, two things:
First, I still think it'd be worthwhile to give it a start-to-finish makeover to better reflect the new layout and interface, so I intend to take up that project here soon! That's going to take a while because it's extremely detailed, but it's coming soon
Second, in the meantime, the text in that blog is still wholly applicable in terms of:

How to review section and test results

What to prioritize when you see particular strengths and weaknesses in LR and RC

The importance of still redoing questions even though you got them right

Noting how others performed on answers based on the percentages shown (are you missing easy or hard questions, and how does your

performance align with your fellow test takers)

Considering pacing and timing details and where you could speed up without sacrificing accuracy

And the value that can be found in getting some assistance if you still feel you're not making the kind of progress you want
So please still use it for guidance as you progress with the Analytics and continue to review your results!
Thanks again for the question and I hope that helps! Keep up the hard work!
