You don't need precision tools to get power metrics from the pico.
All you need is power the pico with a 5V usb charger using an inline USB V and mA meter.
You'll have precision down to (usually around) 50mW or less.

Also, your code to decrease cpu frequency does so in blocks of 10Mhz, with the last block being 10Mhz. The next step would be 0Mz, freezing the device. The last 10Mhz should be tested in 1Mhz decrements, down to 1Mhz, further down 1Mz by 100Hz decrements until you reach 100Hz, which should be absurdly slow.
