[mpiwg-tools] "read, write, and reset" of pvar

P581~582 of the Standard says

"Advice to implementors: Sampling-based tools rely on the ability to call
the MPI tool information interface, in particular routines to start, stop,
read, write and reset performance variables, from any program context,
including asynchronous contexts such as signal handlers. MPI
implementations should strive, if possible in their particular environment,
to enable these usage scenarios for all or a subset of the routines
mentioned above. If implementing only a subset, the read, write, and reset
routines are typically the most critical for sampling based tools."

Does the standard really want to say "read, write, reset" are critical or
should it be "start, stop, read, reset"?
