Parallel wells multiply controlled thermal work units. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.
highlighted = computed this step
Parallel wells are counted
The chip has 4 rows and 3 columns, so it has 12 wells.
Nwells=4⋅3=12
Well cycles multiply controlled work
With 6 cycles, the chip runs 72 well-cycles. Molecular yield is not claimed.
