My strong preference is this be tracked and the considerstions therein
referenced in Experimental Considerations. I have no strong preference what
we actually call it.

I’m fine with ams.cb for “closest break” if that keeps things nice and tidy
for an A-R (i.e. arc=pass ams.cb=1).

I also like it because then we have arc cv and ams cb. But I’m splitting
hairs, and again, don’t really care what it’s called.
