GER30 !W Butterfly to 7600-7400. Is that possible?

My first weekly chart ever :-) I think it is quite probably scenario DAX fall to 7600 or even 7400 to complete butterfly advanced harmonic pattern. Obviously pattern itn't exactly perfect, as B point should be in 78.6% of XA, but in trading nothing is perfect and actually mathematics is great in drug store rather than here :-).
