You bet. You can do hundreds of dives at the same kind of resort while overweighted and out of trim until you are really, really good at diving overweighted and out of trim. You can go into more and more complex wrecks, caverns, and caves without being shown how to do it safely until you find the one you can't get out of. There are all sorts of things you can do without any training at all.
Nah, in my community, we fix those horrible divers that the pro's turn out. But nice attempt to twist my words.
