The crate had to come back to earn again
The pool earned on each completed cycle, yet eight cycles produced less contribution than the twelve I had approved. The investment question remained larger than the movement margin.
The service earned a positive contribution on a completed movement. That statement was true and insufficient. I had approved a model in which twenty thousand crates completed twelve annual cycles. They completed eight in the reviewed year. The difference changed the contribution available to support the capital and other costs, even though the revenue and direct-cost rates per cycle were unchanged. I had to return to the investment question rather than let a useful unit margin stand in for the performance of the asset over time.
