Testing 5-minute micro-sessions vs. weekend cramming

I recently tracked my retention after a hectic work week. Usually, I cram on Sundays, but my recall for new technical terms dropped to 40%. This week, I switched to three 5-minute bursts daily. My retention jumped to 85% despite spending less total time studying. Has anyone else quantified the impact of frequency over duration? My data suggests micro-sessions are significantly more effective for busy schedules.
