I think the 5th way refers to being able to either insert the bare wire through the hole in the screw or simply wrap it around the screw post.
Of course, I'm always open to suggestion.
Isn't that what I said?
Anyway, there's the connectors on the wire itself:
1) Bare Wire
2) Pins
3) Banana Plugs
4) Spades
Then there is how these are attached to the speaker or amp:
1A) Bare wire wrapped around the post
1B) Bare wire insterted through lateral hole in the post
2A) Pins crimped next to the post
2B) Pins crimped through the lateral hole in the post
3) Banana plugs inserted into longitudinal hole in Bolt Cap
4) Spades inserted as spades are supposed to be inserted
2A is never recommended so delete it. That leaves only 5 methods.
Then there is another possible 5<sup>th</sup> way, in which 1A and 1B are only one method because they use only bare wire, 2B, 3, and 4 are three more methods. And the 5<sup>th</sup> way is that the dual binding posts are spaced to accept dual banana plug connectors.
