The shortest answer here is that you can't calculate sampling precision 
for something you didn't sample. So if your rigid bodies were not moved 
during the sampling, you should exclude them from the precision 
calculation, otherwise you'll get overly optimistic estimates for the 
precision.
The longer answer would depend on why you're fixing the rigid bodies in 
the first place.
