2 forward, 1 back
both engines running and stable
No2 95% plus, No1 a positive split
From memory, Not strictly true!
And as you say, "every now and then someone gets it wrong".

Isn't it something like;
Engines must be either both running or both stopped
No1 ECL must be at GRD IDLE
No2 ECL must be at MAX
If both engines are running, ensure No2 engine is above 95% Nf and No1 has a positive Nf split.
Post MOD 720, the Accessory drive switch can function only if the generators are both on-line or both off-line.

Pretty simple, I always thought, but every now and then someone gets it wrong.
Famous last words!
