[Patricio Poblete]

Dear Adam,

Thanks for the clarification. I think that there should not be time on the
IANA side that is unaccounted for. If there is time between steps that
could potentially be significant, I would support computing the total time
spent in the IANA side, in addition to the time spent in each step.

Patricio
