Micro-Sessions vs. Long Blocks for Consistency

I've been experimenting with my study schedule to maintain consistency during busy shifts. I shifted from two 90-minute weekly sessions to spreading 15-minute bursts evenly across my day. Data-wise, my recall rate jumped from 72% to 88% over three weeks. The shorter, high-frequency approach prevents the burnout I felt during long sessions. Have you tracked your performance when forced to switch to shorter windows?
