Thanks for your answer.
Let me clarify my question. My variables are as following:
![3792_pastedImage_2.png 3792_pastedImage_2.png](https://community.jmp.com/t5/image/serverpage/image-id/171iBB041BD649F9FA55/image-size/medium?v=v2&px=400)
I have the possibility of having 18 runs. I could set user specified to 18 or I could change the "Number of Replicate Runs" to 4 which result in 18 runs. Here are the result of both approach:
Specifying 18 in "user specified" field:

change the "Number of Replicate Runs" to 4:
![3790_pastedImage_0.png 3790_pastedImage_0.png](https://community.jmp.com/t5/image/serverpage/image-id/173iC4F220880DA1FBF7/image-size/medium?v=v2&px=400)
Could you please let me know how to decide based on these results.
Thanks!
