Develop Assistant > Exposure Bias/Compensation options?

[BeauRX]

I would like to know what the Develop Assistant > Exposure Bias(option)/Compensation(message) does in APh (1.10.0.244), I am as unclear as the poster below. As the other poster states EC is baked into the pixel data by physically changing the amount of light. The attached image was shot with a +2 EC to make any differences extreme.

EB-ApplyExposureBiasAsDefault - Appears to apply the exposure compensation a second time while setting the slider to zero. With +2EC this saturates most pixels.

EB-ApplyExposureBiasAsInitialState - Appears to apply the exposure compensation a second time while setting the slider to the EC value in the raw file. With +2EC this saturates most pixels. 

EB-TakeNoAction - Self explanatory and my current option.

Assuming Exposure Bias(option) is the same as Exposure Compensation(message)  it would help to use a single term.

Just guessing ... Apply as default means don't show it on the slider, Apply as initial state means show it.

The Help for Developing a raw imagemight provide some insight:

Exposure bias: Choose whether to apply exposure bias value if stored in the raw image's EXIF data. Like Histogram stretch, both 'default' and 'initial' give the same results but reports zeroed or actual values, respectively. The 'Take no action' option ignores the exposure bias value.
