Well, won’t argue about it being obvious, because perception is reality, and if someone tells you it’s not clear, and you tell them they are stupid, then the person that made the mistake is you. (Unless you think I am asking questions just to ask them)
Anyway, you have 3 separate electrical circuits it seems, the frog, and each point rail.
If you are powering the point rails with a wire, then you only need the “single” frog juicer for the frog, not the dual, unless you have 2 turnouts close together.
The Juicers are made down here in San Diego, and was working on a layout with 3 of them last night, strapped as autoreversers though. My friend who was working on the layout with me is a distributor for the juicers.
