There is a NASTY difference
Allow me a small joke.
If I punch a brick wall, eighty times, until every bone in my hand breaks, my Precision is 100%.
MY *Accuracy* is ZERO.
Precision is Repeat-ability.
Accuracy is if it;s actually "semi agreed to be right" (see Middle Ages and Cpoernicus, etc);
So Bigots are Precise. So are mis-aligned machines.
But Chess Lore is built on geniuses who allowed only a couple chances per game, and when the opponents missed them, down they went.
The Lineage is "sorta" Adolf Anderssen, Morphy, Alekhine, Tal, Wildcard Keres, Kasparov, and the "Ice Players" are currently in the lead.(Capablanca, __-, Karpov, Kramnik, Carlsen)
I would hope if the site uses CAPS for anything its able to employ as a batch analyser (multi games at once) and has a much more comprehensive db element. The CAPS issued to members is next to useless, 1 game at a time and starts analysing when still within early db. Also the article mentioning CAPS as a learning tool is massively overselling the deal, ok I made an error, try another move - still weak, ok try again - hey better effort this time, completely hopeless to isolate things down to a given move, but if thats all it can do then ...
