Drift Window Bounds Net

interval, not magic correction

A drifting baseline creates an exact net interval. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

highlighted = computed this step

A drifting baseline is an interval

The measured signal is 20, while the baseline can be between 4 and 6.

The net signal becomes a checked interval

Subtracting the high baseline gives 14; subtracting the low baseline gives 16. The interval width is 2.
