Detector addresses become scheduled readout passes only after channel batching is exact. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Rows and columns set address count
The rendered grid has 4 rows and 5 columns, so the address count is 20.
Naddr=4⋅5=20
Channel batches and repeats are separate factors
Each row divides addresses by active channels before multiplying by repeat reads. The scheduled-pass column is not a hand label.
