I understand that prstat -m shows microstate wallclock utilization that should

Why do you think it should add up? Its not that simple.

For a start, the display you are looking at is process level stats,
and some of the processes are multithreaded, so in a given time
interval each thread can appear/dissapear/wait for stuff as much as it
wants.

The prstat display is accumulating some underlying counters, you are
not seeing the full set of microstates. Probably the easiest way to
get all the data in the format you want is to start with the SE
toolkit process class or msacct.se

Some detailed discussion on the data sources etc can be found here
