How many students can a single turnstile handle?
The answer comes as a number: the gate flow report measures the queue and derives how many gates are needed from your own data.
Detail
A common field observation is that beyond a few hundred students a single turnstile jams in the morning; this varies with the school's entrance layout.
That is why we do not name a gate count from a guess; we measure and show it.
