No, it's just the mod in me wondering why a self confessed DIR practioner shows up in a TDI forum asking about a hyperoxic trimix class. Is he interested in taking the class or interested in starting a debate about the (dubious in my opinion) benfits of using trimix at 120 feet. Given the direction the thread has taken I'll assume the latter - and then if I weren't a mod maybe return the favor by trolling in the DIR zone.
With TDI you can get the full range of styles being taught. Fully DIR compliant to the most anti-DIR combination possible. It is all based on the instructor and TDI standards pretty much allows any/all the different permutations that can be found.
30/30 is a valid standard gas as per GUE and it would be a gas that could be taught in the standard TDI trimix course.
So, basically your post about TDI and DIR means you really do not understand either one.
