To initiate Stayman with garbage hand GIB needs 4450 shape.

 

Here default rebid for GIB is 2NT instead of pass, but simulation showed somehow that pass is also an option.

I think that I approve.

 

It may run counter to the way that the human mind works, but I think that statistically it may well be reasonable for responder a priori to have a game try opposite a 1N opener and yet on the balance of probabilities to prefer 2D over a further game try after the Stayman response.

Correcting 2H to 2S to show 4 spades (NF but invitational) is certainly a good treatment.
