ELO is a FIDE rating, not a USCF rating and especially not a

Nonsense. "All ICCF titles, championships and ratings are recognised
by FIDE." ICCF website. Correspondence players talk about their ELO
ratings all the time. The ICCF even has a rating search engine named
Eloquery.

As for the use of the term "ELO" for "USCF Rating", Mr. Kingston would
not be the first chess player to do so, nor will he be the last.
