With respect to your request for a citation of any "key advocate of the OCT" theory claiming a "perfect match", I knew that I had it somewhere, and here it is.
It seems, according to the citation Jason Colavito credits Bauval himself as having written as early as 1994 that there is an "uncanny precision" between the Gizamids and the belt stars.
Colavito's use of quotation marks suggest he is quoting Bauval directly.
You can read it for yourself here:
where Colavito writes:
Bauval, writing in 1994, had argued that “the pattern of Orion's Belt seen on the 'west' of the Milky Way matches, with uncanny precision, the pattern and alignments of the three Giza pyramids!”
Will that do?
Precision = precise = spot on!
adjective 'uncanny' used here as an intensifier to emphasise the precision being remarkable, striking, deliberate
