Ahh I see. Well if you're using the same colorimeter, screen and program, the discrepancy between each profile created within 10/15 minutes of one another after the proper hour warm up time will be so minimal it's really not worth the bother. There is probably a larger margin of error between the left and right of the screen.
In exact answer to your question, I'm afraid I don't know how to automate the profiling process. However, I know of not one program that has this feature, and I'm assuming for good reason.
