I imagine you'll find that you need a similar concept as well.

I was thinking about this for our design as well. How did you reach the 6" rule? Arbitrary? I was looking at 2.5 times our accuracy. 2 times to account for sampling and .5 as a slush.
It's not a big deal, but I hate to not have a reason. :-)
Thanks.
