Table 1

The differences of transmissibility with two methods.

Calculation step	PV/S	Transmissibility (actual)	Cumulative effect		Eliminate cumulative effects
			MULTX	Transmissibility by the model	MULTX	Transmissibility by the model
Initial value	0	1	1	1	1	1
Step 1	10	1.1	1.1		1.1
Step 2	20	1.2	1.2		1.2
Step 3	30	1.3	1.3		1.3
Step 4	40	1.4	1.4		1.4
Step 5	50	1.5	1.5		1.5

Note: take the formula as an example.
