What he is trying to say about a rule of thumb. Common practice is a few
extra capacitor does not hurt.
Most of the cases filtering is over done and try to compensate for bad
layout, grounding systems....
Nice example is a high-end audio preamplifier, takes about 50 ma current
from the power supply, which was filtered by 22000 uF capacitors....

Can you describe what you see very often that's wrong?
