# There is no default rate list: FINDINGS 50 removed the delivery constant from
# this tree and a sweep that invented one back would be the same mistake with
# more rows. `0` means an unlimited pipe, which measures the RING's ceiling with
# delivery removed as a variable -- an upper bound, not a prediction.
