While observing takeoff for
[[electrical-takeoff#Unit Condensing Units|unit condensing units]],
the project engineer expressed confusion
at the process of calculating average horizontal length,
expressing that it was more complicated than they expected
considering takeoff procedure for similar processes.
The PE asked why we would not simply use the maximum
so that we would not risk having too little overall.

Their expectation surprised me,
since it is intuitive to me
that there must be some limit to the logic of "covering it",
since it is always within our power to add contingency,
and especially because---if anything---
I feel that our procedures tend towards
the upper end of reasonable ECI.

My response was not well formulated.
