You're heading in the right direction, looking @ your fuel log.
my goal with a restrictor plate is not to limit my power use, rather the engines output and consumption.

I am also not trying to reduce pumping losses, this is just adding more restrictions in hopes it might trick the MAF that the engine needs less fuel. Although testing is required.
