Now that you have crossed over, are you sure those are the TDI requirements and not what the person who handled that decided to require? TDI allows an instructor to go beyond the basic requirements.
When I started Tech training with TDI, my instructor told us flat out that he was going to go well beyond the TDI requirements. He did not tell us what the TDI requirements were, and he did not tell us what his requirements were. He only casually mentioned one day that we were well past the TDI requirements already. You will not believe how many months it took me to pass Intro to Tech. After a while I got a little miffed and wanted to get a cert card or two. I wrote to TDI and described what we were being required to do. Their reply was that it sure sounded like I was learning a lot, and I should be happy with it. Now that I am an instructor for those courses and know what is required, I am amazed at how much was added.
Now, it is also possible for an individual instructor to go the opposite direction and require less. It is not allowed by the rules, but how is one to know? A few years ago my niece became a NAUI certified diver by doing one 2-hour pool session and one OW dive to a maximum depth of 10 feet. I am pretty sure NAUI requires more than that, but she has a card.
