A quick v2.0.23 DeltaWave update was published adding a new result to easily compare to the results to those published in the GearSpace thread.

This adds a line to the results tab that will make it easier to compare to the results posted in that thread. Make sure to select Stereo mode if you want results for both, left and right channels. That line starts with text GS: under the results tab.

The result shows delay (in ms), level difference for L and R channels, then the RMS null result for L and R channels. Last, the same RMS null results A-weighted:
