Basics of Running Commuter Railroads/Transit Systems: SMART Smart?

This question is aimed at experts or professionals or fans with knowledge. True knowledge of how railroads work. I'll keep it simple.
SMART owns 14 DMU cars. They can make trainsets of 2 or 3 cars.
SMART is supposed to provide half hourly commute trains during the commute period.
SMART needs to run 6 trainsets in the commute period in order to have trains running every half hour during the commute. The first trainset of the commute can make it back to the originating terminal to turn as the seventh train of the commute.
SMART only runs 4 trainsets presently. Some have three cars. Thus there is a 1.5 hour gap in trains after the fourth train as the first train makes its way back to the originating terminal to turn.
So, basically, SMART planned to run 6 trainsets a day with between 0-2 cars in reserve.
Was this good planning? Does it conform to best practices for a commuter railroad/transit system? Does it make sense? What other commuter railroads only have one or two extra cars on the premises?
