My observation about most of the new spoken Latin courses and lessons is that they're teaching Vulgar Latin or something akin to early medieval Latin. That's cool, and very interesting. As you alluded to, you're basically learning proto-Romance. However, as you likely know, people should not expect to be able to read classical Latin based on that knowledge. They should be able to read many medieval Latin works (including many notable scientific works!), but forget Cicero, Ovid, or Tacitus. Those will require significant additional study.
