Filling Array's and then executing test

[Caleytown]

I currently have a test that pulls data from a spread sheet and stores it in arrays. Because the program I am using has a very slow response time, I need a sec delay between each step (using the Run Mode option at 1 second). Unfortunatly, this causes my loop to pause for a second between each step, making my script double in execution time. Is there any way to make the loop run with no delay but have the rest of the script execute with the delay? Thanks.
