I met my Brother in law and explained to him the issue.

He told me there is exclusively one instance where you can have an exact and errorless assesment for the ptolemaic horoscope, and that's artificial fecondation, where the lab technician puts in contact the male and female cells. This way the time of Conception is imposed.
Otherwise, even with complete medical records, the error is a 2-3 days at best, even when the exact time of mating is known and it is known that it led to Conception, the spermatozoa have a survival time of a few days and the exact time of a succesfull meeting and fusion of the two germinal cells is unknown.

Now this may mean that the part relative to the slower planets (longer orbital times) may still be pretty accurte whereas the faster planet may be unreliable. Also, based on an estimate of the uncertainty of Conception time it would be possible  to determine which are the planets and other factor we cannot use with reliability in the ptolemaic horoscope. I think with a few tests you can have an idea about which part of the horoscope can be used.

Also, I don't know if there have been specific studies but now it would be possible to study comparatively the difference between a ptolemaic and a genetliac horoscope in persons born out of artificial Conception, where the time of Conception is exact. So we'd have accuracy in both Conception and Birth times and the differences in the horoscopes would be due only to the methods.
