Dummy LPAR or milicode waste the cycles - nevermind. My point was there
are some cycles lost, not longer (slower) cycles.

There is no "dummy LPAR". Millicode periodically executes
a loop to waste some time. The logical processor remains dispatched
to the physical processor while that is happening, so the wasted time is
included in the CPU Timer for the logical processor, and thus is charged
to the dispatched work unit, as it should be.

It is simple: clock remains the same for any subcapacity. Simply some
cycles are taken by "dummy LPAR".
How does it relate to CPI? It does not affect...
