A program pulse is applied to a set of non-volatile storage elements. The magnitude of the program pulse is chosen to be low enough such that no non-volatile storage elements will be over programmed. The non-volatile storage elements are tested to determine whether at least one non-volatile storage element (or some other minimum number) has been programmed past a test threshold. If so, the set of non-volatile memory elements is considered to have one or more fast programming non-volatile storage elements and future programming is performed using a smaller increment value for subsequent program pulses. If the set of non-volatile memory elements is not determined to have one or more fast programming non-volatile storage elements, then a larger increment value is used for subsequent program pulses until one non-volatile storage element (or some other minimum number) has been programmed past the test threshold, at which point the smaller increment value is used for subsequent program pulses.
