Throughput is $counter / $measuredTime. Average time is $measuredTime /
$counter. Think about @AuxCounter "OPERATIONS" as the _auxiliary_ operations
counter, in addition to the regular JMH's one.

It's not impossible technically, but the amount of work required to engineer
this is probably not worth it. Non-steady state workloads are weird anyway.
Partial throughput measures get even weirder. You might just want to balance the
number of cache hits/misses and see how the overall performance changes with the
changed mix.
