That's a very high output unit.

Is it enough for 28 units? I don't know but assuming 1/2 filling the tub at the same time is a bit high unless they all work the same shift at the same place.

If I've got a sore tooth I do...

I know the example was over simplified to make the math easy to understand. The point is, even though that's a lot of hot water in one hour, you've got a lot of people demanding it at a peak hour.

Change it up a bit if you want, make it 10 people each taking a 10 minute shower at 2.5 gpm. That's 250 gallons alone. Stretch a few of those of 15 or 20 minutes, and you end up with cold water.

Fortunately for all of those tenants, load diversity calculations apply to plumbing systems in a manner similar to electrical systems. Also, I would imagine if a problems existed at that location, you would have heard about it already! In addition, we have to remember that we start out with 65 gallons of hot water in the tank + whatever number of gallons are in the circulating piping system - could be quite a lot!

Who would I have heard from?
Not all units are sold yet.
