If you want to get the most out of your OEM ignition coil (not individual coil system as on M60), then platinum or IR is nice, but you don't really get more horsepower... you basically reduce the coil's load so each spark plug can produce equal strength power... thereby those +3 HP claim. Hence the test result of less voltage requirement.

If you really want to get the most power out of your ignition system, then you must upgrade your ignition system to Jacob electronics and alikes. They will then tell you to run regular spark plug with increased gap so their igntion coil will be producing the maximum output of 40K+ volts. The more voltage = more power. Jacob electronics also have multiple sparks per cycle so it is doing the quadruple duty of stock ignition system... double power and multiple sparks instead of single spark.
