Depends on the edition of the NEC. That table was removed in the 2014 & 2017 NEC editions and replaced with the 83% rule. Then the 2020 edition brought it back, but it's now Table 310.12 and it carries the caveat that it can only be used when there are no adjustment or correction factors required. It's exactly the same as the document that I attached.
