that does seem like a really short interval but the algorithm doesn't take into account mileage or time (or what kind of oil you use). Just "duty cycle" which doesn't tell you a lot.
Some of the basic parameters are cold starts, restarts, time at operating temperature, engine revolutions, run time, oil temp, coolant temp, etc. Chrysler may have many more, I have never found out exactly; I assume it is a trade secret....
The OCI predicts degradation. You're free to ignore it. If you really want to know you can have your oil tested, for example, at blackstone labs.
