Knowledge is not made more true or false based upon the experience of
the person who holds it.

I respectfully disagree. Knowledge without experience is untested as
witnessed by the statement regarding kellets. Kellets can be useful
for reducing swing radius in a crowded anchorage under moderate
conditions, but do very little to enhance ultimate holding power of an
anchor, any anchor. The reason, as an experienced person would know,
is that the anchor rode, rope or chain, with or without kellet, will be
pulled nearly taut under heavy load.
