USATF won't accept a record set on a course that was not USATF certified as of race day. The reason for this is that the majority of races are run on uncertified, and mostly short, courses. Also, it would be beyond our capacity to measure all these courses after the fact.
I am intrigued by the phrase "presumably accurate." Why would we presume the course to be accurate? Most uncertified courses are not accurate.
The course can certainly be certified "after the fact" but this will affect only future performances, not past ones.
