A final sample ledger shows how address, capture, and day gates combine. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
The first sample record passes every gate
Spacing is 4 m, rows are 4, captures are 12, and days are 2. All three gates accept, so release is 1.
Arows=1,Acap=1,Aday=1,A=1
One extra phase row blocks the release
The second record keeps captures and days unchanged, but row count is 5 instead of 4. The row gate is 0 and release is 0.
Nrows=5=4,A=0
A late throughput row also blocks the release
The third record restores 4 rows and 12 captures, but the target takes 4 days. The day gate is 0 and release is 0.
