Can you explain where these figures come from? 

I understand that they are just default values. I also understand that we are talking about two different links - the link observed, where no more than one packet in 10,000 should be picked by the sampling process, and the link that exports the sampled information where no more than 1/10,000 additional bandwidth should be allowed for each filter on an observed link.

Thanks and Regards,
