if you used analogy of Price as crash, price pattern A could be a car crash, pattern B a plane crash, etc.

you have an interesting thought going on there.
but how is this different from the statistical odds of a part-formed Shoulder and Head pattern resulting a fulfilled or failed Head and Shoulders pattern.
Or the odds of a 1-2-3 reversal, or support or resistance holding or failing.

At least the partly-formed pattern of a 1-2-3 or Sup/Res has internal logic, whereas the proximity of PatternA to Pattern B seems arbitrary.
