post-block interim performance feedback insensitive to direction errors

Hi - looks like during both practice and experimental blocks, the feedback slide that summarizes that block's performance does not code directional Go errors (e.g., pressing left when the stim is a right arrow) when calculating "missed Go proportion". Meaning, if a subject presses right for left arrow and left for right arrow the entire block, the missed Go proportion will read "0.0 (should be close to 0)".
The data output accurately reflects the directional errors as incorrect, and stop trials accurately code responses of either direction as errors.
Just wanted to bring this up in case I'm misunderstanding what constitutes a "missed Go" trial. I would imagine that it would be any incorrect Go response, whether it may be an outright omission or wrong key (especially since the feedback slide encourages the subject to continue the same pattern of responses). Am I wrong about this?

Thanks!
Ahmet

Edit: I now see that we can choose to display the "incorrect Go proportion", which is more in line with what I mentioned above. I still wonder if there is a reason for missed Go trials being the go-to choice for performance feedback here.
