My point was if the ALT BAT terminal is wired directly to the battery(as it is) then why run another wire along the exact same path? If that was needed then how does a 1 wire alternator provide the correct amount of charge? -- It senses the load demand and charges accordingly thru a self exciting regulator.Most of these alternators require about 1000-1200 Alternator RPM (around 600-700 engine rpm) to initiate charging

Actually any amount of charge is acceptable above about 12.5V.Most Chrysler products operate on a 13.3 system at idle(approx 600 rpm with headlights and a/c off)

14.5V is an optimum amount of charge, not a necessity. If you're charging at 15.5V you are overcharging and could be damaging crutial systems-for example if my EFI system started charging higher than 14.7 then I could expect premature failure of critical components.

GM wired millions of vehicles without that wire, so I would assume they're smarter than me and I'll follow their lead.
