I have used the board room analogy for surge protectors into UPSs as using a
stack of coffee filters in the coffee maker basket.  If one filter is good,
then 10 should be great, right ?  But what happens, you impede the proper
flow through the filter.

I know, a crude analogy that is not technically accurrate to the details,
but prevents the Charlie-Brown's Teacher (wahhhh-wahhhh-wah-wah )effect when
I speak.
