Readout throughput is a product of instrument count factors. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

A run has throughput factors

The toy run has 4 lanes, 5 reads per lane, and 100 bases per read.

lanes=4,reads=5\text{lanes}=4,\quad \text{reads}=5

Bases per run are a product

Multiplying the three factors gives 2000 bases per run. Read quality and assembly are outside this model.
