When I checked out as a brand new 727 F/E back in 2000, our CKAs made sure we know that thing COLD, inside and out. There was zero confusion from day 1.

So maybe they’re just not training it the way they used to. Once you understand the TPS it’s a piece of cake. I think what you mean to say is, they need to teach it better.
