You might be right, perhaps not needed for the Sim, but I have witnessed type-rated line pilots who clearly had no clue how G/Smini works or what it does, and they almost panic when the speed bug jumps 20kts up and down on approach.
They seem to think the auto-thrust is going wrong and sometimes take it out and fly the old fashioned way - constant IAS - not realising that that is more dangerous, without a fixed IAS increase above Vapp.
Sim rarely has turbulence or wind gradients on approach
