"Real," standard pole bending is always the same pattern. 21 feet from the timer to the first pole, and 21 feet in between poles. The only variable that would affect time *should* be footing, but some arenas are small and squash the timer too close to the first pole, messing up the time and shortening the pattern.
Then, of course, you run down, weave six poles up and back, and run home. The record time, as someone else said, is in the mid-19 second range. Anything below a 21 second, however, is very, very good.
