If you are looking for synonyms for the phrase "more intermittently," there are several options to choose from. "Occasionally," "sporadically," and "infrequently" are all viable alternatives that convey a similar meaning. "Irregularly" and "choppily" also work, as they suggest an inconsistent or disrupted pattern.
