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):

Time (s) Multiplier
0.02 0
0.04 0.1
0.06 0.25
0.08 0.5
0.1 1
0.12 0.5
0.14 0.25
0.16 0.1
0.18 0

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:

Time (s) Loda (lbf/ft/ft)
0.02 0
0.04 800
0.06 2000
0.08 4000
0.1 8000
0.12 4000
0.14 2000
0.16 800
0.18 0

Thank you!
