I looked back at my original post and see nothing controversial or argumentative.
All I said was for folks using autoexposure cameras, the difference between nominal and actual f-stop is inconsequential.
If I select 4.5 (aperture priority), the camera may select a shutter speed somewhere between 1/250 and 1/500. Actually it records the shutter speed in decimal seconds.
If I use shutter priority, the camera uses continuously variable aperture settings.
So It doesn't care what the actual transmission factor might be.
Any version of ID consistent with all the evidence is indistinguishable from evolution.
