Hi Since the data comes out of the box in percent, the whole “counts” thing is a bit of a fiction. The conversion to counts or bits was done based on observations of earlier boxes. That conversion may or may not apply to the 3810/11/12’s. Right now, there’s no reason to think that it’s wrong for these boxes. I’d just be careful watching the data.
