First of all, there is no such thing as a combination of a double zigzag and a triple zigzag for wave W or any other wave. That's BS, don't know where you heard that this is a possible count.

And waves c can never be a triple zigzag. WTF? c must always be a 5 wave impulse unless in a triangle.

WXY cannot subdivide as wxy... please tell me who taught you this BS. I hope that you did not read that in a book.

You should read my next post about BTC for sure.
