At smaller ports of entry, a superintendent could be overseeing more than one. That is primarily because in some cases they are fairly close to each other and are ports of entry where there are still two border service officers at a time, at the very least, on a shift. Each of the border service officers is having to hold the others accountable. Like anybody in their day-to-day job, there is not somebody watching over what they're doing every second of the day.
We're hiring our border service officers with the intention that they will have the integrity required and expected of them, and a superintendent is available to them at any point in time. They're not always physically seeing the superintendent, because they are shared between smaller ports of entry.
