This is a great answer! And to be honest, much better than I was expecting.
Thanks!
I was wondering, what would it take to get a clarification like this on all
of the missions? I certainly don't want you to write up something like this
for each one--that would take forever. But if this head referees conclave
meeting produces a product like that, is it something that can be shared?
