What does the strands mean?
And for the dual coil twisted idk if I'm doing something wrong but it says at 50watts it'd be 139.
I got the same conclusion on the single twisted as you did Though.
Strand are the number of wires that you are twisting together, you can ignore the pitch twist as long as you leave it at 0 but create your twisted wire with a drill. Otherwise you have to measure...
Not quite sure what you mean by a single twisted. Little help on that one please?
