semi-regular
Not quite consistent
Semi-regular describes something that occurs or appears with some regularity but not on a fixed or predictable schedule: semi-regular meetings, a semi-regular column in the magazine.
It suggests more consistency than occasional but less than regular.
The term also has technical meanings in mathematics and crystallography for patterns with partial but incomplete regularity.
