Hasta La Motion!

I am pretty new to RealFlow (2012), in general, but wanted to do something a bit more advanced. Currently, I am working on a project that involves a water splash and a double helix growing out of it. I already have the splash simulation done and the double helix as two different files and was going to combine them using a bin loader. Where I am having trouble is retiming the simulation.

Right where the splash reaches it’s peak, I need to slow it down (t/9) and then have it resume at normal speed so I can do some camera movements in maya. So I have been trying to use retimer to basically stretch frames 15-20 to 15-179 and then have it resume to normal speed after.

I just really don’t know how to stretch just part of the simulation successfully and wanted to see if anyone had any pointers. I have tried an if statement, but pretty sure my equation is completely wrong.

if(14<t<21,1,t/9)

Any help is much appreciated! Thanks in advance!
