I'll ask again...what is the make-up of the students in the course? Military, security, police, ex-military bodyguards etc. or "average joes". If it is average joes, why would any of them (yourself included) need to aspire to reach "phase three" where you would be learning techniques for which you would have little to no use of no matter how bad a situation you found yourself in...unless you were actually using them as part of your job.
I think this is where the sport/street/RBSD classes are really all forms of self-delusion...most of the time we do them for FUN. Sure there are techniques, tactics and training at each one which have total application to self-defense but at least in BJJ we acknowledge that it is largely a competitive sport (with some great real world applications). I think where the RBSD communities can really get off tangent is when they ultimately fail to acknowledge that they too are really a form of sport/fun and in some ways just as self-deceptive in their insistence that they are "real". Sure if you are in the military some of this is "real" but for "Jack from suburbia" learning how to track and silently assasinate or capture an unwarry target is nothing more than dress-up (again albeit a fun one and one with SOME practical applications).
