It was stated in my just-completed Fundies class that GUE assumes that your CNS loading % decreases by 50% after a 90 minute SI. I checked the NOAA diving manual whence the single and 24 hour CNS % dive time limits are given (that GUE and every other agency AFAIK uses), but nowhere in the chapter or anywhere else in the book is this mentioned, let alone explained. Some other sources have implied that the NOAA time limits were derived empirically rather than theoretically. Can anyone point me to the source of the GUE "1/2 reduction in CNS % after 90 minute SI"? I'm assuming this is based on something more exacting than 'TLAR'.
