Is it safe to infer that dogs may be trained to run cold blinds using several different drills, the list of which may include some or all of the above?

Can we state simply, that; T,TT, Star, W, 3 Legged etc. are just tools to achieve an end (Cold Blinds) and that the care with which each is taught, the correction protocol and the mainenance of a clear standard of performance is more critical to the enhansment of the skill than the drill?
