JPac, I'll 2nd Kevin's comment. It's not the number of dives, it's how you look and feel in the water. I've trained divers in cavern diving with only a couple dozen dives. I've also trained divers in cavern with several hundred dives. If you feel comfortable in the water and have a good handle on your buoyancy and trim, especially while task loaded, then you'll do fine. Kevin also makes another good point - get out there and do the dives and practice the skills in between courses. You only get an introduction to the skills in the courses. My students don't come out of my courses having perfected the skills. That's impossible to do in a weekend. What I do know is they have done the skills enough that the muscle memory is starting to build. They have the foundation to get out there and practice those skills over the next few months and work on getting them as close to perfect as possible. What determines whether you get a card from me in most situations is your attitude, not how well you do the skills. Yes, you do have to perform the skills to a satisfactory level, but even if you were to perform them perfectly, if your attitude sucks, you don't get a card. Fortunately, the agency I teach through allows me to do that.
Finally, are you diving doubles yet? If so, great, then you're probably ready now. If not, then I suggest doing a intro to tech or intro to doubles course. I've taken a diver who never had a dive in doubles to intro cave level in 2 weekends and he did great. You can play around with doubles and work at getting your trim and buoyancy right over the next 30-40 dives or you can speed up the process a little with a good instructor/mentor who will help you address the common problems most divers experience when first transitioning to doubles.
Let me know if you have any more questions. If you ever head over to the Florida panhandle, let me know.
