Metrics Decoder Documentation?

Is there any documentation about Metrics Decoder? Of course Kernel Profiling Guide document it but not enough.
For example, I want to know the detail of Pipelines (ADU/ALU/CBU/FMA etc) relation ship for performance tuning.

Reference
https://docs.nvidia.com/nsight-compute/ProfilingGuide/index.html#metrics-decoder

We don’t have more detailed description on these pipelines than what is already stated in the profiling guide. What is your use case that requires to have more detailed descriptions, in order to make progress in optimizing your kernels?

Thank you for your suggestion.
following messages are appeared on Nsight Compute Warning. I will digging on it.
