Does MwRSF have an option about the steel backed timber guardrail transition?

I'm not sure that a formal report was ever created for that test.
Further, I cannot find any documented analysis or testing that illustrates the crashworthyness of the steel-backed timber guardrail installed with a tight radius. As such, I
