Load scale for SN sequential Simsolid

Hi

I would like to ask if there is any rule to apply load scale in Simsolid SN Sequential sequence setup ?

For example, if it assumed the stress study was set up with 20kN static load. This implied that when fully reversed, the alternating stress amplitude was actually 40kN. So is that the scale factor is 2 ? Or there is other thing it should be counted when it is applied the load scale in simsolid?
