If Wave Three is less than a 1.618 Fibonacci extension of Wave One, expect Wave Five to relate to the length of  Wave 0 to 3 added to Wave Four.

When a Wave Five is extended,  the 1st projection will equal the  length of Wave 0 to 3 added to  Wave Four.

And the  2nd projection will equal 1.62  times the length of Wave 0 to 3  added to Wave Four.
