Deriving a better idle predictor is a bit orthogonal to fast idle.

It would be a good idea to set the fast idle threshold to be the
same as intel_idle would use on that platform and rerun the benchmarks

Then the Cx pattern should be mostly identical, and fast idle can be
evaluated on its own benefits.
