The search feature is at the bottom of the page. Time is only affected by the weight of the butts, not how many.
If a butt weighs 7lbs it takes X time, if a butt weighs 9.8lbs it will take X time. I have done 40lbs of butts on my UDS and depending on each butts weight it took different times (bigger butts longer, smaller less time)
