PartWhse table CountedDate vs LastCCDate

If I’m understanding correctly the LastCCDate is the date the part was created or the last date the part was cycle counted, where the CountedDate is the last date the part was cycle counted or blank if the part was never cycle counted. Is my understanding correct?

I want to know the last date the part was cycle counted or if it has never been cycle counted, so if my understanding is correct I should be using the CountedDate.
