That's why I said I would need to check that out. But I can see where 
the logic goes. If your device can only measure to 2.5D then how can 
you calculate lower than that with a measurement from your device? 
Consider that 2.5D is about 0.5% of the light reflected back into the 
device, that's pretty small. He also said that at that end of the 
scale, really small measurement variations make a huge swing in the 
reported density.
