Dynamic Multiplier

Hello,

How does dynamic multiplier work? I read about in the manual but I see results in my analysis that don't correspond to my dynamic load set up. Let's say I set up dynamic load as qy,start,ref= - 8000lbf/ft/ft, and then I set up the Dynamic Multiplier as in table below (without static load):

Then, if I set up "Dynamic time" as 0.9s (in the Phase set up), will this process be repeated (5 times because 0.18*5=0.9)?

Also, will the load be  applied as:

Thank you!
