You know that whole piece of advice to skip those turdy substitution questions?

Well. Look. I just did that in a section. Saw it, said NO THANKS, boxed it, moved on, didn't care. Had a tish of extra time, came back to it, still didn't care, eliminated some AC's, pulled the trigger. Nothing to lose, possible 1 point to gain.

-0. That would NOT have happened if I had wasted time on this Q, friends. Was tighter on time in this section than I'd like to be; if I'd wasted the likely 2min+ had I gotten sucked into that vortex, I wouldn't have gotten to one or two questions at the end due to the confidence sink these substitution questions often entail, time sink aside.

Just an example of how following one little bitty piece of 7sage wisdom can result in a real difference of a couple of points.

So, in summary ...

PS: It was thanks to @Pacifico who recently was advocating for this on the BR calls. This is why we listen to Pacifico.
