1" center spacing is 13'3" prototype.  I would do a test to see how well your fingers/eyes deal with 1" spacing for straight track. 1 1/8" to 1 1/4" on curves.

Did you measure your fingers?

 

LION just accepots what the geometry of his switches gives him.

 

Well, not exactly, LION has been known trim turnouts to fit.

The angles of the diverging paths will go a long way to determining at what separation you end up running all three of them parallel to each other.  You must begin to curve them back from the diverging angle as soon as possible if you want the most narrow separation, but that could present some trouble for the rolling stock or the locomotives.  This is one instance where you want to mock it up temporarily and see how little you can get away with before you get derailments caused by couplers reaching their hard limits of sway.

Alternatively, use a larger frog number so those curves from diverging back to parallel are less troublesome (and lose some siding length as payment).

NMRA Standard S-8 is a good place to start. Recommended track spacing in curves varies by the type of equipment and sharpness of the curve.
