I agree with both of you: 2.02.40 p.1 How to proceed tells us in item 3 to enter with airport pressure altitude. And there is no more word about QNH correction. And sound mental logic leads to just transforming QNH to pressure altitude.
But

, read 2.02.24 p.2 Example 2, where it is clear, that after reading Tflex on the QRT you should correct it for QNH.
I think, that there is no need, because we entered QRT with
actual pressure altitude. Correction according to 2.02.24 is to be when we entered with standart elevation.
Spasibo, I think it is right. Or not?
