Actual time per treatment vs. what the software estimated?

I just finished 5 CK treatments for an acoustic neuroma that measured 2.0 cm x 1.3 cm on the MRI that was done for treatment planning a few days before the treatments started. (A 3rd dimension was not specified on the radiologist's report). Before the 1st treatment started I asked the CK technician how long the treatment will last. She told me the software says 40 minutes. From the time she told me on the intercom that everything was lined up and the treatment was starting, until the time she told me it was done, seemed like less than 40 minutes to me. I mentioned that to her and she said it ended up only taking 30 minutes. The remaining 4 treatments also took 30 minutes each. I would think the software could pretty accurately predict the time, given that it knows how many beams to shoot (137 in my case), the angles and the movements it has to make. What could account for it only taking 30 minutes instead of the estimated 40? I'm probably being paranoid, but 30 minutes seems like a little short compared to what I have seen others write about their treatment times. Is 30 minutes per treatment reasonable for a 2.0 cm x 1.3 cm AN? Thanks.
