Genome-scale output is a repeated instrument-day budget with exact target closure. 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 one-day target starts with run output
The first instrument row uses 2 lanes, 5 reads per lane, and 100 bases per read, giving 1000 bases per run. Its day budget is 2000 bases, so the 2000 base target takes 1 day.
Brun=2⋅5⋅100=1000,D=2000/2000=1
More lanes and instruments make the target two days
The second row gives 2000 bases per run and 12000 bases per day. The target is 24000 bases, so the exact duration is 2 days.
Brun=4⋅5⋅100=2000,D=24000/12000=2
The third row makes target days visible
The last row produces 2400 bases per run and 14400 bases per day. A target of 43200 bases therefore takes 3 days. The scan shows project scale as repeated physical readout, not a caption-only claim.
