The same pair of channels passes or fails as the required floor changes. Exact arithmetic here means exact results for the stated model inputs; measured inputs still carry uncertainty and significant-figure limits.

Resolution compares separation with the floor

Line A is at channel 11 and line B is at channel 14. Their separation is 3 channels against floor 2, so resolved is 1.
