Personally, not heard of that Elliott Wave rule before. Seen many truncated failed fifth waves which have not completely erased the entire prior impulse.
Good!
I get this example on that page:

sorry, I see you have written a new lettering.
Although the example may not be correct, the text does refer to the Elliot Wave theory
Cuando se produce un fallo de 5 volveremos al origen del impulso y además de forma violenta. Si no fuera así, el recuento será incorrecto.
When a failure of 5 occurs we will return to the origin of the impulse and also violently. If not, the count will be incorrect.
Sorry but I am more confused with your labeling, how can the ABC correction be larger than the previous impulse?
