can you please expand on "factor"

[xf15]

in the code you have

%       'factor'    the BioSemi EEG normalization factor for converting the
--
19 | %                   TRF to microvolts (524.288mV / 2^24bits)

the factor in speech_data.mat is 0.0313

where these numbers come from? what do they mean?

I am aware that 524.288 * 10^3 / 2^24 = 0.0313

without factor

with factor

seems that factor shrinks predicted response to realistic micro voltage...
still wonder what happened during modeling that needed this correction
