Looking good overall.
I would just say that if you're dropping SSDT CpuPm + SSDT CpuI0st and injecting the CPU PM ssdt table, then you should not have PluginType parameter checked. It's either or. But that should not impact battery life in any way. I did not see anything relating to a dGPU so I can only presume there is none and your config is optimum as far as CPU power management and battery life is concerned.
